Hilda Solis stepping down as labor secretary

Hilda Solis announced that she is stepping down from her post as labor secretary, CBS News has confirmed. She sent a letter to President Obama today notifying him of her retirement.

Solis was nominated to the position the same day the president was inaugurated in 2009, serving through the president's entire first term. She ran the Labor Department during the worst economic recession since the Great Depression. The department, which calculates unemployment statistics, came under criticism during the presidential campaign for a steep drop in the jobless numbers from above 8 percent to below 8 percent right before Election Day.

President Obama called her "a critical member" of his economic team who has helped put "millions" of people back to work. "Hilda Solis has been a tireless champion for working families," the president wrote in a statement.

Before her current position, she was a member of Congress, representing California since 2001 but left that job to be the first Hispanic woman to run the agency.

The president must now name a replacement that must go through the Senate confirmation process. CBS News learned today that the president intends to nominate his chief of staff, Jack Lew, to run the Treasury Department.

Solis joins Secretary of State Hillary Clinton, Treasury Secretary Timothy Geithner, CIA Director David Petraeus and Defense Secretary Leon Panetta in stepping down from their cabinet-level posts.

A White House official says Health and Human Services Secretary Kathleen Sebelius, Veterans Affairs Secretary Eric Shinseki and Attorney General Eric Holder plan to remain in their positions.

White House Won't Rule Out $1 Trillion Coin

White House Press Secretary Jay Carney today flatly ruled out any negotiations with Congress over raising the debt ceiling, but there’s one odd-ball solution he would not rule out:  minting trillion dollars coins to pay off the debt.


“There is no Plan B. There is no backup plan. There is Congress’s responsibility to pay the bills of the United States,” White House Press Secretary Jay Carney told reporters at the daily White House briefing.


READ: $1-Trillion Coins: The Ultimate Debt Ceiling End-Around?


Asked if the administration would rule out minting trillion dollars coins if Congress fails to act, Carney deflected saying “you could speculate about a lot of things.”


“Nothing needs to come to these kinds of… speculative notions about how to deal with a problem that is easily resolved by Congress doing its job, very simply,” he added.


Pressed further on why they won’t offer a clear yes-or-no answer to the question, Carney referred questions to the Treasury Department.


“I answered it thoroughly,” he later joked. “And I have no coins in my pocket.”


Some have suggested the President could invoke the 14th Amendment to the Constitution – which states, “the validity of the public debt of the United States … shall not be questioned” – and ignore the debt ceiling altogether.  On that question, Carney has offered a straight answer:  the 14 Amendment does not apply to the debt ceiling.


“We just don’t believe that it provides the authority that some believe it does,” Carney said.


The trillion-dollar-coin idea has been floated by, among others, an economist at the American Enterprise Institute.


Here’s our full Q and A:


KARL: I heard you unequivocally rule out using the 14th Amendment on the debt ceiling. I heard you unequivocally rule out negotiating with Congress. But you did not rule out this trillion-dollar coin idea. So can I ask you just a yes-or-no question? Does the White House rule out the idea of minting trillion-dollar coins as a way of dealing with the debt ceiling?


CARNEY: I would refer you to Treasury for the specifics of this question. I can tell you that the president does not believe that there is a backup plan or a plan B or an off-ramp. The only viable option here is Congress to fulfill its — that Congress fulfills its responsibility and ensures that the United States of America pays its bills, as it has always paid its bills throughout its history.


KARL: But why have we ruled out the 14th Amendment and not ruled out the trillion-dollar coin idea?


CARNEY: Again, I can tell you that there are no back-up plans. There are no plan B’s. I’d refer you to the Treasury.



KARL: Jay, the speaker of the House has made it perfectly clear that he is willing to increase the debt ceiling, but the principle is for every dollar the debt ceiling is increased, a dollar of spending must be cut. Given that you’re saying that the White House will not negotiate on raising the debt ceiling, are you willing to accept that principle from the speaker, a dollar in cuts for every dollar increase?


MR. CARNEY: I think the president’s been very clear that his absolute principle is that we need to reduce our deficit in a balanced way that does not shift all the burden, through cuts exclusively, on senior citizens, on families who have disabled children, on families who are trying to send their kids to school. That’s just unacceptable.


You know, one of the things we learned in the process that we just went through late in — late last year is that when it comes to specificity, we never saw any specificity from Republicans in terms of how exactly they would achieve the kind of sweeping cuts that they say they want and out of whose — you know, from whom would they demand that payment.


And what the president has been very clear about is he will not negotiate on Congress’ responsibility to pay its bills. He will negotiate and is willing to compromise, as he has demonstrated repeatedly, when it comes to moving forward in a balanced way to reduce our deficit. We have to deal with the sequester. We have to deal with a variety of budgetary and economic and fiscal challenges.


But he will not negotiate over the debt ceiling. And the threat itself is a problem, as we saw in the summer of 2011. The binary choice that Republicans seem to want to present to the American public is either we gut Medicare and Social Security or we tank the global economy. I’m not a communications director for the speaker of the House or the Senate minority leader, but I would think selling that would be very hard.


KARL: But help me understand how this works. You say you will not negotiate on this issue. They’ve put out a principle, so they produce something — and they say they will — that cuts a dollar for every dollar increase. And you’re saying you won’t negotiate on that?


MR. CARNEY: Have you seen that?


KARL: Well, this is what they say they are going to go forward.


MR. CARNEY: Well, I mean, you know –


KARL: So either –


MR. CARNEY: — words are not actions, and there has been, at — to this date, very little specificity, you know, since we — since the Ryan plan, which itself was lacking in specifics. And if their — if their position is we’re going to voucherize Medicare or tank the global economy, they should say so. That is unacceptable to the American people. It’s certainly unacceptable to the president.


Look, here’s the thing. Congress has the authority to authorize money, right, not the president. Congress racked up these bills. Congress has to pay these bills. We are very interested in a discussion and negotiation about getting our fiscal house in order. This president has already signed into law over $2 trillion in deficit reduction. He is eager to do more in a balanced way.


But it is not appropriate to — in this president’s view — to say that if I don’t get what I want, I’m not going to raise the debt limit. That is basically saying, I will abandon the history of the United States maintaining the full faith and credit of its currency and its — and its treasury by refusing to pay bills because I didn’t get what I want politically.


And that’s just not acceptable to the president.


KARL:  I’m not sure I understand how that works — you’re not going to negotiate at all? –


MR. CARNEY: We’re not going to negotiate. Congress has a — if Congress wants to give the president the responsibility to raise the debt ceiling, he would take it, as we saw when — in 2010 or — I forget, there have been so many of these confrontations — in — when — in 2011 when the so-called McConnell plan was adopted, you know. But they assigned themselves this responsibility. They need to be — the fact that they, you know, assigned it to them is something that they have to deal with. They assigned it to themselves, they need to act, and they need to, without drama or delay, raise the debt ceiling. We still have — there is plenty of opportunity outside of threatening the full faith and credit of the United States to debate fundamental differences over our economic and fiscal policy proposals, but it is not wise to do that around raising the debt ceiling, not wise to do it around the simple principle that we, the United States of America, pay our debts.

Pruney fingers give us better grip underwater









































WHY do our fingers do prune impressions when soaked? It could be an adaptation that gives us better grip underwater.












Fingers and toes wrinkle in water after about 5 minutes due to the constriction of blood vessels. This reduction in volume pulls the skin inward, but as the skin's surface area cannot change, it wrinkles. A study in 2011 showed that wrinkles form a pattern of channels that divert water away from the fingertip – akin to rain treads on tyres. The team thought that this could aid grip.












To find out, Tom Smulders and his team at Newcastle University, UK, timed people as they transferred wet or dry objects from one box to another with and without wrinkled fingers.












With wrinkles, wet objects were transferred about 12 per cent faster than with unwrinkled fingers. The time it took to transfer dry objects was the same regardless of wrinkles.












So why aren't our digits always prune-like? "With wrinkles, less of your skin surface touches the object, so there may be issues of sensitivity," Smulders suggests.

Relatives sob as US massacre 911 calls heard in court






CENTENNIAL, Colorado: Relatives wept in court Tuesday as frantic 911 calls were played from a US theater shooting that killed 12 people last year, as prosecutors closed their case for the alleged gunman to face trial.

The court heard how suspected killer James Holmes purchased more than 6,000 rounds of ammunition in the months before last July's shooting in Colorado, and rigged up elaborate booby-traps at his apartment.

Defense lawyers will call witnesses Wednesday, the third day of hearings, to decide if there is enough evidence for Holmes to go on trial. They are expected to highlight his mental instability as a possible reason he should not do so.

In the first of 41 harrowing emergency calls made in a 10-minute period in Colorado, 30 loud booms could be heard in less than half-a-minute, making it difficult for the 911 dispatcher to distinguish what was being said.

In another, six minutes after the first call was logged at 12:38 am, 14-year-old Kaylan Bailey told the emergency operator her two cousins had been shot, and that one of them did not appear to be breathing.

"We need to start CPR (cardio-pulmonary resuscitation) on your cousin who's not breathing," said the operator.

"I can't hear you," responded Bailey, as chaos unfolded in the theater in Aurora, where Holmes -- clad in body armor and a mask -- threw at least one smoke-bomb type device before opening fire in the early hours of July 20.

The hearings opened Monday with officers choking back tears as they recalled scenes after the slaughter, which left 12 dead and 58 injured by gunshots at a packed midnight screening of the Batman film "The Dark Knight Rises."

The Aurora massacre revived the perennial US debate over gun control -- an issue re-ignited even more intensely by last month's shooting of 20 young children at a Connecticut elementary school.

Tuesday's hearing heard testimony from federal firearms supervisor Steven Beggs that Holmes made at least 16 purchases from May to July 2012 including four firearms, incendiary devices and almost 6,300 rounds of ammunition.

Holmes's lawyers could argue that he is mentally unfit to stand trial.

Defense attorney Tamara Brady asked Beggs: "Is there any process in Colorado to screen out purchases by a severely mentally ill person?"

"No," replied Beggs, who detailed the purchases made online and in person by Holmes.

FBI bomb technician Garrett Gumbinner said Holmes told investigators after being arrested that he had booby-trapped his apartment, in an attempt to draw emergency responders away from the theater shooting site.

Officers found a trip wire at the door of his home, rigged to set off flame and sparks that would catch the gasoline-soaked carpet and go on fire.

There were six-inch fireworks shells filled with improvised thermite, a hot-burning explosive.

"You can't put it out with water," Gumbinner told judge William Sylvester. There were also three containers of improvised napalm, 11 bottles of gasoline and other chemicals intended to act as fire accelerants, he said.

There were three systems in the apartment intended to initiate the explosive devices, including one linked to a trash bag near the apartment dumpster by a remote control.

Curious behavior by Holmes during police questioning was also recounted: At one point he tried to stick a metal staple into a power socket. At another he played hand puppets with gloves that had been put on him to preserve evidence.

Prosecutors are trying to build up their case that the shootings were a premeditated act of mass murder, and identifying Holmes as the lone shooter.

Supporting that strategy, Aurora police officer Tom Welton testified that Holmes made postings on two dating websites earlier in July, asking "Will you visit me in prison?"

Prosecutors wrapped up their evidence in the hearing by listing all the victims by name, the injuries they suffered and the charges -- more than 160 in all -- filed on behalf of each.

Opinion: Time for tough talk with Karzai




The last time Presidents Obama and Karzai met was in May in Kabul, when they signed a pact regarding U.S. troop withdrawal.




STORY HIGHLIGHTS


  • Afghan President Karzai meeting with President Obama in Washington this week

  • Felbab-Brown: Afghan politics are corrupt; army not ready for 2014 troop pullout

  • She says Taliban, insurgents, splintered army, corrupt officials are all jockeying for power

  • U.S. needs to commit to helping Afghan security, she says, and insist corruption be wiped out




Editor's note: Vanda Felbab-Brown is a senior fellow in foreign policy at the Brookings Institution. Her latest book is "Aspiration and Ambivalence: Strategies and Realities of Counterinsurgency and State-Building in Afghanistan."


(CNN) -- Afghan President Hamid Karzai is meeting this week with President Obama in Washington amid increasing ambivalence in the United States about what to do about the war in Afghanistan.


Americans are tired of the war. Too much blood and treasure has been spent. The White House is grappling with troop numbers for 2013 and with the nature and scope of any U.S. mission after 2014. With the persisting corruption and poor governance of the Afghan government and Karzai's fear that the United States is preparing to abandon him, the relationship between Kabul and Washington has steadily deteriorated.


As the United States radically reduces its mission in Afghanistan, it will leave behind a stalled and perilous security situation and a likely severe economic downturn. Many Afghans expect a collapse into civil war, and few see their political system as legitimate.


Karzai and Obama face thorny issues such as the stalled negotiations with the Taliban. Recently, Kabul has persuaded Pakistan to release some Taliban prisoners to jump-start the negotiations, relegating the United States to the back seat. Much to the displeasure of the International Security Assistance Force, the Afghan government also plans to release several hundred Taliban-linked prisoners, although any real momentum in the negotiations is yet to take place.

Washington needs to be careful that negotiations are structured in a way that enhances Afghanistan's stability and is not merely a fig leaf for U.S. and NATO troop departure. Countering terrorism will be an important U.S. interest after 2014. The Taliban may have soured on al Qaeda, but fully breaking with the terror group is not in the Taliban's best interest. If negotiations give the insurgents de facto control of parts of the country, the Taliban will at best play it both ways: with the jihadists and with the United States.


Negotiations of a status-of-forces agreement after 2014 will also be on the table between Karzai and Obama. Immunity of U.S. soldiers from Afghan prosecution and control over detainees previously have been major sticking points, and any Afghan release of Taliban-linked prisoners will complicate that discussion.










Karzai has seemed determined to secure commitments from Washington to deliver military enablers until Afghan support forces have built up. The Afghan National Security Forces have improved but cannot function without international enablers -- in areas such as air support, medevac, intelligence and logistical assets and maintenance -- for several years to come. But Washington has signaled that it is contemplating very small troop levels after 2014, as low as 3,000. CNN reports that withdrawing all troops might even be considered.


Everyone is hedging their bets in light of the transition uncertainties and the real possibility of a major security meltdown after 2014. Afghan army commanders are leaking intelligence and weapons to insurgents; Afghan families are sending one son to join the army, one to the Taliban and one to the local warlord's militia.


Patronage networks pervade the Afghan forces, and a crucial question is whether they can avoid splintering along ethnic and patronage lines after 2014. If security forces do fall apart, the chances of Taliban control of large portions of the country and a civil war are much greater. Obama can use the summit to announce concrete measures -- such as providing enablers -- to demonstrate U.S. commitment to heading off a security meltdown. The United States and international security forces also need to strongly focus on countering the rifts within the Afghan army.


Assisting the Afghan army after 2014 is important. But even with better security, it is doubtful that Afghanistan can be stable without improvements in its government.


Afghanistan's political system is preoccupied with the 2014 elections. Corruption, serious crime, land theft and other usurpation of resources, nepotism, a lack of rule of law and exclusionary patronage networks afflict governance. Afghans crave accountability and justice and resent the current mafia-like rule. Whether the 2014 elections will usher in better leaders or trigger violent conflict is another huge question mark.


Emphasizing good governance, not sacrificing it to short-term military expediencies by embracing thuggish government officials, is as important as leaving Afghanistan in a measured and unrushed way -- one that doesn't jeopardize the fledgling institutional and security capacity that the country has managed to build up.


Karzai has been deaf and blind to the reality that reducing corruption, improving governance and allowing for a more pluralistic political system are essential for Afghanistan's stability. His visit provides an opportunity to deliver the message again -- and strongly.

USADA head: I got death threats during Armstrong probe

(CBS News) Travis Tygart is the head of the U.S. Anti-Doping Agency, which polices U.S. Olympic sports. Lance Armstrong won the world's most grueling event, the Tour de France, seven times. But after Tygart's investigation, Armstrong lost all of his titles. In his first interview, Tygart spoke with us for the premier of a new program, "60 Minutes Sports" on Showtime. Tygart says Armstrong was doping in his very first win at the Tour de France in 1999. The drug was EPO, which boosts endurance.

TRAVIS TYGART: Six samples that were taken from Lance Armstrong were retested in '05. And they were positive.

SCOTT PELLEY: In '99, when the tests were originally taken, was it reported that they were negative?

TYGART: There was no test for EPO. They were not tested for EPO at that time.

PELLEY: And when you tested for them in 2005, you discovered that they were --

TYGART: All six were flaming positive.

PELLEY: Flaming positive?

TYGART: Flaming positive.

Armstrong allegedly offered large "donation" to doping agency
Atty. denies report Lance Armstrong will admit doping
Lance Armstrong sued for more than $1.5M by U.K. newspaper over libel case

Tygart told Pelley that throughout the investigation, witnesses were intimidated to try to keep the code of silence from breaking.

PELLEY: Was Lance Armstrong personally involved in intimidating these other riders to keep them quiet?

TYGART: He was. It was tough. All -- all these witnesses were -- were scared of the repercussions of them simply telling the truth.

PELLEY: What could Lance Armstrong do to them?

TYGART: Incinerate them.

Former teammate Levi Leipheimer felt the heat. In his sworn affidavit, he says he came to a cycling dinner after he testified to the grand jury. Leipheimer says Armstrong was there and sent Leipheimer's wife a text that read, "Run don't walk."

PELLEY: What did she take it to mean?

TYGART: It's a veiled threat. Knowing her husband had just testified, truthfully, in front of the grand jury and had told citizens of this country about this great fraud. It was a message: You better run.

PELLEY: Your investigation showed that there were personal threats made against riders who had decided to come clean. I wonder if there were any threats against you.

TYGART: There were, Scott.

PELLEY: These threats came from where?

TYGART: Emails, letters.

PELLEY: Anonymous?

TYGART: Yeah.

PELLEY: Can you remember any of the lines from the emails or the letters?

TYGART: The worst was probably putting a bullet in my head.

PELLEY: Did you take that seriously?

TYGART: Absolutely.

To hear the rest of Travis Tygart's story, tune into the premiere edition of "60 Minutes Sports" tomorrow at 10:00 p.m. on the Showtime Network.

CIA Nominee May Have 'Zero Dark Thirty' Problem


ap movie Zero Dark Thirty  thg 130103 wblog John Brennans Zero Dark Thirty Problem

Navy SEALs are seen fighting through a dust storm in the new thriller directed by Kathryn Bigelow, "Zero Dark Thirty." (Columbia Pictures/AP Photo)


There’s only one White House staffer portrayed in the new movie “Zero Dark Thirty,” and it is someone described in the credits as “National Security Advisor.”


It’s a position that’s possibly filled in real life by John Brennan, the president’s counterterrorism advisor, who President Obama nominated Jan. 7 to be director of C.I.A.. The character in the movie, with references to the C.I.A’s involvement in the flawed intelligence on weapons of mass destruction that led the U.S. into war in Iraq, explains to a frustrated agency representative the difficulty of the president’s decision in acting on partial intelligence.


Spoiler alert: The president does ultimately act on that partial intelligence and Osama bin Laden is nabbed.


The character in real life – Brennan – has been opposed by some for his work at the C.I.A. under President Bush and the “enhanced interrogation” policies like waterboarding that also play a prominent role in the movie.


President Obama makes a cameo in the movie in the form of a “60 Minutes” interview in which he declares that, “America doesn’t torture, and I’m gonna make sure that we don’t torture.”


That declaration is viewed, in the film, by a table full of CIA agents in Pakistan who have been involved in “enhanced” interrogations.


The U.S. used waterboarding on three al Qaeda detainees at secret prisons run by the CIA.  It  ended the practice of using secret prisons in September of 2006 under President Bush and in 2009 President Obama signed executive orders in his first days in office that banned of the use of waterboarding and other “enhanced interrogation” techniques.


But that was after the techniques had already scuttled Brennan’s first chance to head the CIA.  Brennan wasn’t nominated to be CIA director back in the early days of the Obama administration, but he was widely considered to be a front-runner for the job. ABC’s Jake Tapper reported at the time that Brennan withdrew his name for consideration and most of the opposition came as a result of his work at the C.I.A. when those techniques were in use.


And there is indication that they will make his nomination difficult this year.


“I appreciate John Brennan’s long record of service to our nation, but I have many questions and concerns about his nomination to be Director of the Central Intelligence Agency, especially what role he played in the so-called enhanced interrogation programs while serving at the CIA during the last administration, as well as his public defense of those programs,” said Sen. John McCain after Brennan was nominated Monday.  ”I plan to examine this aspect of Mr. Brennan’s record very closely as I consider his nomination.”


The movie has certainly brought “enhanced interrogation” – it’s critics call it torture – back into the conversation about the war on terror, as ABC’s Lee Ferran reported Monday:


Last week three high-powered senators, Intelligence Committee Chairman Dianne Feinstein (D.-Calif.), Armed Services Committee Chairman Carl Levin (D.-Mich.) and 2008 Presidential candidate John McCain (R.-Ariz.), revealed they had written two letters to Morell in December demanding to know what impact the CIA may have had on the depiction of enhanced interrogation in the film and whether the agency “misled” the filmmakers into thinking the tactic was effective.


“As you know, the film depicts CIA officers repeatedly torturing detainees. The film then credits CIA detainees subjected to coercive interrogation techniques as providing critical lead information on the courier that led to the [bin Laden] compound,” one letter says. “The CIA cannot be held accountable for how the Agency and its activities are portrayed in film, but we are nonetheless concerned, given the CIA’s cooperation with the filmmakers and the narrative’s consistency with past public misstatements by former senior CIA officials, that the filmmakers could have been misled by information they were provided by the CIA.”


Brennan, for his part, has said he opposed torture techniques, as Jake Tapper reported back in 2008 when Brennan removed his name from consideration for the C.I.A. job in 2008.


In a letter released to the media, apparently by Brennan or someone operating on Brennan’s behalf, the former CIA official wrote, “It has been immaterial to the critics that I have been a strong opponent of many of the policies of the Bush Administration such as the preemptive war in Iraq and coercive interrogation tactics, too include waterboarding. The fact that I was not involved in the decision making process for any of these controversial policies and actions has been ignored. Indeed, my criticism of these policies within government circles why I was twice considered for more senior-level positions in the current Administration only to be rebuffed by the White House.”


But Brennan did defend the practice in news media interviews when he described the actions of C.I.A. director George Tenet. This is what Brennan told CBS’s Harry Smith about enhanced interrogation in 2007: “The CIA has acknowledged that it has detained about 100 terrorists since 9/11, and about a third of them have been subjected to what the CIA refers to as enhanced interrogation tactics, and only a small proportion of those have in fact been subjected to the most serious types of enhanced procedures….There have been a lot of information that has come out from these interrogation procedures that the agency has in fact used against the real hard-core terrorists. It has saved lives. And let’s not forget, these are hardened terrorists who have been responsible for 9/11, who have shown no remorse at all for the deaths of 3,000 innocents.”


Brennan has also spoken out in support of “rendition” – the practice where the U.S. government captures terror suspects in one country and relocates them to another. That’s a practice still employed by the Obama administration, according to a recent Washington Post investigation.

World's oldest pills treated sore eyes








































In ancient Rome, physicians treated sore eyes with the same active ingredients as today. So suggests an analysis of pills found on the Relitto del Pozzino, a cargo ship wrecked off the Italian coast in around 140 BC.













"To our knowledge, these are the oldest medical tablets ever analysed," says Erika Ribechini of the University of Pisa in Italy, head of a team analysing the relics. She thinks the disc-shaped tablets, 4 centimetres across and a centimetre thick, were likely dipped in water and dabbed directly on the eyes.












The tablets were mainly made of the zinc carbonates hydrozincite and smithsonite, echoing the widespread use of zinc-based minerals in today's eye and skin medications. Ribechini says there is evidence that Pliny the Elder, the Roman physician, prescribed zinc compounds for these uses almost 250 years after the shipwreck in his seminal medical encyclopaedia, Naturalis Historia.












The tablets were also rich in plant and animal oils. Pollen grains from an olive tree suggest that olive oil was a key ingredient, just like it is today in many medical and beauty creams, says Ribechini.












The tablets were discovered in a sealed tin cylinder called a pyxis (see image above). The tin must have been airtight to protect its contents from oxygen corrosion.












"Findings of such ancient medicines are extremely rare, so preservation of the Pozzino tablets is a very lucky case," says Ribechini.












The cargo of the wreck, discovered in 1989, is rich in other medical equipment, including vials and special vessels for bloodletting. This suggests that one of the passengers may have been a physician.

Hagel draws fire as Obama's Pentagon pick






WASHINGTON: US President Barack Obama named Chuck Hagel on Monday to lead the Pentagon, setting up an ugly confirmation battle as Republican opponents said he was too hard on Israel and too soft on Iran.

Obama's choice of John Brennan to replace scandal-tainted David Petraeus as CIA chief was seen as more straightforward despite the counter-terrorism czar's defense of "enhanced interrogation techniques" and the US drone war.

The second term revamp of the president's national security team was expected to win ultimate approval but several leading Republicans signaled they would make it tough for Hagel even though he is one of their own.

Obama paid particular tribute to retiring Pentagon chief Leon Panetta before giving ringing endorsements to the "outstanding" Hagel and Brennan and urging the Senate not to dally in confirming their important appointments.

"Chuck Hagel is the leader that our troops deserve. He is an American patriot," the president said, heaping praise on a war hero who was awarded two Purple Heart medals for his bravery as a soldier in Vietnam.

"When Chuck was hit by shrapnel, his brother saved him. When his brother was injured by a mine, Chuck risked his life to pull him to safety. To this day, Chuck bears the scars -- and the shrapnel -- from the battles he fought in our name," Obama said.

Some Republicans have never forgiven him for his outspoken criticism of ex-president George W. Bush's handling of the Iraq war, and his closeness to the Democratic president sees him regarded by others as a traitor.

But Obama, who wants to be remembered as a leader who ended wars abroad to set about the tricky task of nation-building at home following a crippling recession, described Hagel as someone perfectly fitted to that mold.

"Maybe most importantly, Chuck knows that war is not an abstraction. He understands that sending young Americans to fight and bleed in the dirt and mud, that's something we only do when it's absolutely necessary," he said.

Administration appointments are often tense affairs in the United States as confirmation hearings provide senators with opportunities to turn away unwanted candidates or score cheap political points, or both.

Hagel, 66, known for a fiercely independent streak and a tendency to speak bluntly, is expected to get particularly rough treatment due to his criticism of America's "Jewish lobby" and opposition to some Iran sanctions.

Republican Senator Lindsey Graham said Hagel would be "the most antagonistic defense secretary towards the state of Israel in our nation's history."

Another Republican senator, John Cornyn of Texas, said he would oppose the nomination, charging it would be the "worst possible message we could send to our friend Israel and the rest of our allies in the Middle East."

But in an interview with The Lincoln Journal Star, a newspaper in his home state of Nebraska, Hagel hit back at his critics.

There is "not one shred of evidence that I'm anti-Israeli, not one vote (of mine) that matters that hurt Israel," he said.

If confirmed by the Senate, Hagel will have to manage major cuts to military spending while wrapping up the US war effort in Afghanistan and preparing for worst-case scenarios in Iran or Syria.

Serving as an enlisted man who never joined the officer ranks, Hagel carries a particular empathy for the unheralded infantry "grunts" in the field.

As he grapples with budget pressures, the former sergeant will likely try to shield frontline troops from the effect of spending cuts.

In his typical straight-shooting fashion, Hagel has called the Defense Department "bloated" and said that "the Pentagon needs to be pared down."

Obama, smarting from watching Susan Rice -- reportedly his first choice to succeed Hillary Clinton as secretary of state -- fold her bid in the face of Republican opposition, pressed hard for the Senate to approve Hagel.

"He would be the first person of enlisted rank to serve as secretary of defense. One of the few secretaries who had been wounded in war and the first Vietnam veteran to lead the department," Obama said, calling his appointment "historic."

Brennan, 57, may get an easier ride but is sure to face questions over his support for the use of certain "enhanced interrogation techniques" under the Bush administration and for his staunch defense of the US drone program.

The 25-year Central Intelligence Agency veteran, an Arabic-speaking Middle East expert, replaces Petraeus, who resigned in November after confessing to an extramarital affair with his biographer Paula Broadwell.

Obama highlighted what he called Brennan's incredible work ethic, saying "John is legendary even in the White House" and reminding everyone of a now-famous quote from August 2010.

Asked if he got any down time or was all work and no play, Brennan replied: "I don't do down time."

In a moment of levity at the White House event, the avuncular 74-year-old Panetta drew loud laughs when he said he would be retiring to his walnut farm and "dealing with a different set of nuts."

Marijuana use is too risky a choice







STORY HIGHLIGHTS


  • David Frum: Casual use of marijuana shouldn't be a reason to lock people up

  • He says there are serious risks to brain development, mental health in using marijuana

  • Frum says it's better to send simple message that marijuana is illegal

  • He says too often social rules become so complex many people can't navigate them




Editor's note: David Frum, a CNN contributor, is a contributing editor at Newsweek and The Daily Beast. He is the author of eight books, including a new novel, "Patriots," and his post-election e-book, "Why Romney Lost." Frum was a special assistant to President George W. Bush from 2001 to 2002.


(CNN) -- Last week, I joined the board of a new organization to oppose marijuana legalization: Smart Approaches to Marijuana. The group is headed by former U.S. Rep. Patrick Kennedy and includes Kevin Sabet, a veteran of the Office of National Drug Control Policy under President Obama.


The new group rejects the "war on drugs" model. It agrees that we don't want to lock people up for casual marijuana use -- or even stigmatize them with an arrest record. But what we do want to do is send a clear message: Marijuana use is a bad choice.

There are many excellent reasons to avoid marijuana. Marijuana use damages brain development in young people. Heavy users become socially isolated and perform worse in school and at work. Marijuana smoke harms the lungs. A growing body of evidence suggests that marijuana can trigger psychotic symptoms that otherwise would have remained latent.


It's possible to imagine a marijuana rule that tries to respond precisely to such risk factors as happen to be known by the current state of science. Such a rule might say: "You shouldn't use marijuana until you are over 25, or after your brain has ceased to develop, whichever comes first. You shouldn't use marijuana if you are predisposed to certain mental illnesses (most of which we can't yet diagnose in advance). Be aware that about one-sixth of users will become chronically dependent on marijuana, and as a result will suffer a serious degradation of life outcomes. As yet, we have no sure idea at what dosage marijuana will impair your ability to drive safely, or how long the impairment will last. Be as careful as you can, within the limits of our present knowledge!"


Yet as a parent of three, two exiting adolescence and one entering, I've found that the argument that makes the biggest impression is: "Marijuana is illegal. Stay away." I think many other parents have found the same thing.


When we write social rules, we always need to consider: Who are we writing rules for? Some people can cope with complexity. Others need clarity. Some people will snap back from an early mistake. Others will never recover.



"Just say no" is an easy rule to follow. "It depends on individual risk factors, many of them unknowable in advance" -- that rule is not so easy.


Richard Branson: War on drugs a trillion-dollar failure


Over the past three decades, and in area after area of social life, Americans have replaced simple rules that anybody can follow with complex rules that baffle large numbers of people.


Consider, for example, the home mortgage. Once the mortgage was a very simple product. Put 20% down, then sign up for a fixed schedule of payments over the next 30 years. In the space of a single generation, these 30-year fixed-rate amortizing mortgages turned what had been a nation of renters into a nation of homeowners.



The goal of public policy should be to protect ... the vulnerable from making life-wrecking mistakes in the first place.



For more sophisticated buyers, however, the standard mortgage was a big nuisance. For them, bankers developed more flexible products: no money down, no documentation, interest-only, adjustable rate. These products met genuine needs. But as they diffused down-market, they became traps for people who did not understand the risks they were accepting.


Consider how we finance higher education. Once, state governments subsidized their universities to offer a low tuition fee to all comers. Fee increases at private universities were constrained by the lower fees at the public institutions: Duke can raise its price only so high above the University of North Carolina. The universities soon realized, however, that by setting their tuition fees low, they were forgoing revenues that might be collected from the most affluent students. Universities rapidly raised their tuition fees, then offered discounts and aid to students in need.


Kevin Sabet: Legalize Pot? No, reform laws


But while anybody could understand a $500 per semester tuition bill, the new system of rebates confuses the very people who most need help.


A few days before Christmas, Jason DeParle of The New York Times reported a depressing example of the toll modern financial aid exacts upon students from less sophisticated backgrounds. He told the story of three bright girls from poor families who had recently tried -- and failed -- to gain college degrees. One of them was admitted to Emory, a prestigious school with a full-ticket price of $50,000, but one that grants very generous financial aid -- if the student can figure out how to make the financial aid work for her.










The trouble was that students who most need aid are often precisely those who have nobody around them who has ever successfully navigated a complicated bureaucratic institution like a university financial aid office.


"Though Emory sent weekly e-mails -- 17 of them, along with an invitation to a program for minority students -- they went to a school account she had not learned to check," DeParle wrote.


"Angelica reported that her mother made $35,000 a year and paid about half of that in rent. With her housing costs so high, Emory assumed the family had extra money and assigned ... an income of $51,000. ... (Angelica) discovered what had happened only recently."


Unable to cope with the school's e-mail system or to decrypt its rules for imputing family income, Angelica finally dropped out of Emory, burdened by $61,000 in student debt.


In 1943, Vice President Henry Wallace published a book celebrating the coming "century of the common man." That century did not last very long. We have transitioned instead into the era of the clever man and clever woman. We have revised our institutions, our programs, our rules in ways that offer profitable new chances to those with cultural know-how -- and that inflict disastrous consequences on those who are overwhelmed by a world of ever-more-abundant and ever-more-risky choices.


Opinion: The end of the war on marijuana


We're not going to uninvent the no-money-down loan. Universities that receive applications from all over the planet cannot finance themselves like an old-fashioned state land-grant college. But we need to recognize that modern life is becoming steadily more dangerous for people prone to make bad choices.


At a time when they need more help than ever to climb the ladder, marijuana legalization kicks them back down the ladder. The goal of public policy should not be to punish vulnerable kids for making life-wrecking mistakes. The goal of public policy should be to protect (to the extent we can) the vulnerable from making life-wrecking mistakes in the first place.


There's a trade-off, yes, and it takes the form of denying less vulnerable people easy access to a pleasure they believe they can safely use. But they are likely deluding themselves about how well they are managing their drug use. And even if they are not deluded -- if they really are so capable and effective -- then surely they can see that society has already been massively re-engineered for their benefit already. Surely, enough is enough?
