Obama hands drone war guidelines to US lawmakers

WASHINGTON: President Barack Obama will hand lawmakers classified documents outlining the legal justification for drone strikes which kill US citizens abroad who are conspiring with Al-Qaeda.

An administration official disclosed the move on Wednesday on the eve of a Senate hearing on Obama's nomination of his top White House anti-terror advisor John Brennan to lead the Central Intelligence Agency in his second term.

Some senators had warned Brennan's confirmation could be in doubt if the administration did not share more information on the legal and constitutional grounding for the US government killing its own citizens.

The disclosure also comes after NBC News published an unclassified Justice Department white paper covering similar ground, reigniting the debate about the killing of estranged Americans who switched sides in the "War on Terror."

"Today, as part of the president's ongoing commitment to consult with Congress on national security matters, the president directed the Department of Justice to provide the congressional intelligence committees access to classified Office of Legal Counsel advice related to the subject of the Department of Justice White Paper," an administration official said.

Obama aides insist killing Al-Qaeda suspects, some of them US citizens, in places like Pakistan or Yemen, complies with US law and the Constitution, even when no intelligence links the targets to specific attack plots.

"We conduct those strikes because they are necessary to mitigate ongoing actual threats, to stop plots, to prevent future attacks and, again, save American lives," said White House spokesman Jay Carney said Tuesday.

"These strikes are legal, they are ethical, and they are wise."

Among the most controversial of the attacks were the September 2011 killings in Yemen of Anwar al-Awlaki and Samir Khan, which stoked concern because the pair were both US citizens who had never been charged with a crime.

Obama agrees to give drone documents to Congress

By Lesa Jansen, CNN

updated 8:27 PM EST, Wed February 6, 2013

The U.S. MQ-9 Reaper unmanned aircraft vehicle has been used to take out key targets in the war on terror.

STORY HIGHLIGHTS

• The move comes on the eve of confirmation hearings for CIA director nominee John Brennan


• The drone program has been shrouded in secrecy, which has been criticized by senators


• The policy paper will go to congressional intelligence committees

Washington (CNN) -- Amid new controversy over his administration's targeted killing of American citizens overseas by drones, President Barack Obama has yielded to demands that he turn over to Congress classified Justice Department legal advice seeking to justify the policy, an administration official said.

The president's move comes on the eve of confirmation hearings Thursday for his CIA director nominee John Brennan and amid complaints from senators, including several Democrats, about secrecy surrounding the drone policy.

"Today, as part of the president's ongoing commitment to consult with Congress on national security matters, the president directed the Department of Justice to provide the congressional Intelligence committees access to classified Office of Legal Counsel advice related to the subject of the Department of Justice White Paper," an administration official said.

The 16-page white paper -- titled "Lawfulness of a Lethal Operation Directed Against a U.S. Citizen who is a Senior Operational Leader of Al Qaida or an Associated Force" -- is a policy paper rather than an official legal document.

Memo backs U.S. using lethal force against Americans overseas

The president, the official said, was turning over the information because he believes the scrutiny and debate is healthy.

Celebrities call on Congress to back gun control measures

Tony Bennett, Chris Rock, Adam Scott, Amanda Peet and other celebrities today joined joined a coalition of elected officials, law enforcement officers, physicians and others on Capitol Hill in support of President Obama's plan to reduce gun violence.

Celebrities team up for gun control action

"I still haven't gotten over Connecticut," Bennett said, referring to the mass shooting at Sandy Hook Elementary School in Newtown, Conn., that left 20 children and seven adults dead.

In the wake of that tragedy, Mr. Obama has called on Congress to pass a series of gun control measures, such as a ban on assault weapons and universal background checks for gun purchasers. He has also gone on the road to build public support for his agenda.

"I'm just here to support the president of the United States," comedian Chris Rock said. "The president and the first lady are kind of like the mom and the dad of the country, and when your dad says something, you listen. And when you don't, it usually bites you in the ass later on."

The celebrities were joined by public figures such as Kerry Kennedy, the late Robert Kennedy's daughter.

"I was four years old when my uncle, President Kennedy, was killed by a man with a gun. I was eight years old when my father, too, was gunned down," she said. "It is almost impossible to describe the pain of losing your father to a senseless murder, or the anger and fear of knowing that murder might have been avoided if only our leaders had acted to stop the violence."

While several celebrities were on Capitol Hill today to back the president, not everyone in Hollywood supports his agenda. Actor Bruce Willis, star of the violent "Die Hard" movies, told the Associated Press he's against new gun control laws that could infringe on rights guaranteed by the Second Amendment. He also dismissed any link between Hollywood gun violence and real-life gun violence.

Armstrong May Testify Under Oath on Doping

Facing a federal criminal investigation and a deadline tonight to tell all under oath to anti-doping authorities or lose his last chance at reducing his lifetime sporting ban, Lance Armstrong now may cooperate.

His apparent 11th-hour about-face, according to the U.S. Anti Doping Agency (USADA), means he now might testify under oath and give full details to USADA of how he cheated for so long.

"We have been in communication with Mr. Armstrong and his representatives and we understand that he does want to be part of the solution and assist in the effort to clean up the sport of cycling," USADA CEO Travis T. Tygart said in a written statement this evening. "We have agreed to his request for an additional two weeks to work on details to hopefully allow for this to happen."

The news of Armstrong's unexpected possible cooperation came a day after ABC News reported he was in the crosshairs of federal criminal investigators. According to a high-level source, "agents are actively investigating Armstrong for obstruction, witness tampering and intimidation" for allegedly threatening people who dared tell the truth about his cheating.

The case was re-ignited by Armstrong's confession last month to Oprah Winfrey that he doped his way to all seven of his Tour de France titles, telling Winfrey he used performance-enhancing drugs throughout his career and then lied about it. He made the confession after years of vehement denials that he cheated.

WATCH: Armstrong's Many Denials Caught on Tape

If charges are ultimately filed, the consequences of "serious potential crimes" could be severe, ABC News legal analyst Dan Abrams said -- including "possible sentences up to five, 10 years."

Investigators are not concerned with the drug use, but Armstrong's behavior in trying to maintain his secret by allegedly threatening and interfering with potential witnesses.

Armstrong was previously under a separate federal investigation that reportedly looked at drug distribution, conspiracy and fraud allegations -- but that case was dropped without explanation a year ago. Sources at the time said that agents had recommended an indictment and could not understand why the case was suddenly dropped.

"There were plenty of people, even within federal law enforcement, who felt like he was getting preferential treatment," said T.J. Quinn, an investigative reporter with ESPN.

The pressures against Armstrong today are immense and include civil claims that could cost him tens of millions of dollars.

Armstrong is currently serving a lifetime ban in sport handed down by the U.S. Anti-Doping Agency, and today was the deadline he was given to cooperate under oath if he ever wanted the ban lifted.

Asian markets rebound, weaker yen boosts Tokyo

HONG KONG: Asian markets climbed Wednesday following big losses in the previous session, with Tokyo surging as the yen tumbled after Bank of Japan governor Masaaki Shirakawa said he will step down early.

Traders also took a lead from Wall Street and Europe, where encouraging economic data offset concerns over political uncertainty in Spain and Italy.

Tokyo soared more than three per cent to a 33-month high, Sydney added 0.84 per cent, Seoul gained 0.19 per cent, Hong Kong added 0.62 per cent and Shanghai was up 0.10 per cent.

Wellington was closed for a public holiday.

Japanese foreign exchange traders welcomed Shirakawa's announcement that he would step down on March 19, about three weeks before the end of his term.

It fuelled expectations that Prime Minister Shinzo Abe will likely fill the post with someone who shares his ideas on aggressive monetary easing that would see more yen pumped into the economy.

The Japanese currency tumbled in New York. By the end of trade Tuesday the dollar bought 93.61 yen and the euro was at 127.13 yen, compared with 92.28 yen and 124.67 yen earlier in the day in Tokyo.

In early Tokyo trade on Wednesday the dollar bought 93.55 yen and the euro fetched 127.06 yen.

The euro was also at $1.3581, compared with $1.3582 in New York and much stronger than the $1.3489 Tuesday in Tokyo.

Major Japanese exporters have been raising their earnings outlooks thanks to recent weakness in the yen, heartening investors.

"Global markets continue to normalise, allowing risk-on trading to resume," said SMBC Nikko Securities general manager of equities Hiroichi Nishi.

"This is partially reflected in the fall of the yen," he told Dow Jones Newswires.

Regional markets resumed their upward trend after suffering a heavy jolt on Tuesday after Spain's Prime Minister Mariano Rajoy was forced to deny corruption claims.

A surge in the polls for the party of former Italian premier Silvio Berlusconi, who has said he would roll back recent austerity measures, spooked markets ahead of an election this month.

However, encouraging data showed US services sector activity rising and the contraction in eurozone business activity decelerating.

Wall Street rebounded after diving Tuesday as the Dow sits close to record highs. The Dow ended 0.71 per cent higher, the S&P 500 climbed 1.04 per cent and the Nasdaq rose 1.29 per cent.

In Europe markets on Tuesday recovered some of the huge losses suffered in the previous session.

Oil prices fell, with New York's main contract, light sweet crude for delivery in March, shedding 12 cents to $96.52 a barrel and Brent North Sea crude for March delivery slipping a cent to $116.51.

Gold was at $1,672.11 at 0230 GMT compared with $1,678.01 late Tuesday.

Tsunami detected after quake strikes near Solomon Islands

The center of the quake was located some 360 miles east-southeast of Honiara, capital of the Solomon Islands.

STORY HIGHLIGHTS

• NEW: Evacuations are ordered for some coastal residents of New Caledonia, Loyalty Islands


• A 1-meter high tsunami was generated near the Solomon Islands, geophysicist says


• No immediate reports of damage or injuries

Editor's note: Are you there? Send your story, images to iReport

(CNN) -- An 8.0-magnitude earthquake struck off the Solomon Islands in the South Pacific early Wednesday, the U.S. Geological Survey reported, triggering a tsunami.

A tsunami warning was issued for the Solomon Islands, Vanuatu, Nauru, Papua New Guinea, Tuvalu, New Caledonia, Kosrae, Fiji, Kiribati, and Wallis and Futuna, according to the Pacific Tsunami Warning Center.

A tsunami watch was in effect for more places: the Marshall Islands, Howland and Baker, Pohnpei, Tokelau, Samoa, Kermadec Islands, New Zealand, American Samoa, Tonga, Australia, Niue, Cook Islands, Indonesia, Wake Island, Chuuk, Jarvis Island, Guam, Northern Marianas, Palmyra Island, Yap, Johnston Island, Minamitorishima and Pelau.

Brian Shiro, a geophysicist at the Pacific Tsunami Warning Center, told CNN that instruments near the Solomon Islands indicated that a tsunami was in fact generated. It is 1 meter high, he said, describing it as "significant."

The event seems to be localized to the region, Shiro said, and authorities are still waiting to see if they want to expand the alert.

The New Caledonia High Commission in the capital of Noumea ordered the immediate evacuation of coastal residents on the eastern coast of New Caledonia and the Loyalty Islands.

The center of the quake was located some 360 miles east-southeast of Honiara, the capital of the Solomon Islands, the USGS said. It was reported to be 3.6 miles deep.

The main quake was preceded by a 6.3-magnitude quake in the region and was followed by several others, the largest of which had a magnitude of 6.6, the USGS said.

There were no immediate reports of damage or injuries.

CNN's Dave Alsup contributed to this report.

Triple amputee vet takes on skydiving, alligator wrestling

(CBS News) HIRAM, Ga. -- When CBS News met Todd Love last year, he was learning how to kayak, and that's no small accomplishment, because Love is a triple amputee. As a U.S. Recon Marine in Afghanistan two years ago, he lost both legs and his left forearm to a landmine.

Love said then that kayaking didn't completely satisfy his need for adventure.

Watch: CBS News first met Todd Love when he was learning how to kayak, at left.

"I want to go skydiving soon," he said. "It shouldn't be a problem to do that."

He was right. Since then, he's done four tandem jumps and hopes to eventually dive solo.

And that wasn't the end of his wish list.

"I've always wanted to wrestle an alligator," he said.

Todd Love took on skydiving to satisfy his need for adventure.

Animal Planet got word of that and invited Love to appear on "Gator Boys."

"The whole time, I was kind of thinking, 'I hope this gator doesn't get tired of me being on top of him, 'cause I'm bite-sized,'" Love said.

Love also recently became a fully certified scuba diver.

"I feel like I can do anything I put my mind to," he said. "And for me, that's way more than having two legs. It's priceless."

He put his mind to surfing and was doing handstands within minutes.

And he can't get enough of the demolition derby -- in a car he controls by hand. Love said that was the most intense of all his activities.

"I would say the adrenaline rush was probably the most significant," he said. "It's up there with combat."

His next adventure: going to college. It makes him more nervous, he said, than jumping out of a plane, but he's determined to succeed.

Love doesn't spend a lot of time feeling sorry for himself.

"I don't have a reason to feel sorry for myself," he said. "A lot of times, no conversation at all, people will come up to me and thank me for my service, and I see the tears in their eyes and there's not much that I can say. In my mind, I'm thinking I wish these people knew -- I wish they knew what I was thinking, how much I love my life."

Love said he's always on the lookout for a new adventure and predicted he'll still be doing "something crazy" when he's 90 years old.

White House: Drone Strikes on Americans 'Legal'

Feb 5, 2013 3:54pm

The White House today defended the use of targeted drone strikes against U.S. citizens abroad suspected of high-level terrorist activity, but declined to detail the criteria for ordering such an attack.

“Sometimes we use remotely piloted aircraft to conduct targeted strikes against specific al Qaeda terrorists in order to prevent attacks on the United States and to save American lives,” White House Press Secretary Jay Carney told reporters.

“We conduct those strikes because they are necessary to mitigate ongoing actual threats, to stop plots, to prevent future attacks and, again, save American lives. These strikes are legal, they are ethical, and they are wise,” he said.

U.S. Air Force

Administration lawyers found it is lawful to kill an American citizen if a “high-level” government official believes the target is an operational leader of al Qaeda who poses “an imminent threat of violent attack against the United States” and if capture is infeasible, according to a newly disclosed Justice Department document.

The 16-page white paper, first obtained by NBC News, finds there “exists no appropriate judicial forum to evaluate these constitutional considerations” and that the administration does not need to present evidence to a court before or after ordering such an attack.

“The condition that an operational leader present an ‘imminent’ threat of violent attack against the United States does not require the United States to have clear evidence that a specific attack on U.S. persons and interests will take place in the immediate future,” the document reads.

Carney repeatedly declined to discuss the details of the white paper.

“I would point you to the ample judicial precedent for the idea that someone who takes up arms against the United States in a war against the United States is an enemy and therefore could be targeted accordingly,” he told ABC News’ Jon Karl.

“[The president] takes his responsibility as commander in chief to protect the United States and its citizens very seriously. He takes the absolute necessity to conduct our war against al Qaeda and its affiliates in a way that’s consistent with the Constitution and our laws very seriously,” he said.

The white paper is believed to be a summary of the reported classified memo that outlined the legal justification for the drone attack that killed American-born radical cleric Anwar al-Awlaki in September 2011.

The American Civil Liberties Union has called the newly discovered document “profoundly disturbing.”

“It’s hard to believe that it was produced in a democracy built on a system of checks and balances. It summarizes in cold legal terms a stunning overreach of executive authority — the claimed power to declare Americans a threat and kill them far from a recognized battlefield and without any judicial involvement before or after the fact,” ACLU National Security Project director Hina Shamsi said in a written statement.

The Obama administration has carried out more than 300 CIA drown strikes in Pakistan, far more than his predecessor, President George W. Bush, according to the Bureau of Investigative Journalism.

Pressure is building from Capitol Hill for the White House to outline its legal authority to kill American citizens in counterterrorism operations.

“It is vitally important… for Congress and the American public to have a full understanding of how the executive branch interprets the limits and boundaries of this authority,” a group of eleven bipartisan Senators wrote in a letter to the president Monday, “so that Congress and the public can decide whether this authority has been properly defined, and whether the President’s power to deliberately kill American citizens is subject to appropriate limitations and safeguards.”
