Obama said, "It's important for everybody to remember that our shared border is more secure than it's been in years."

"We want to make sure we look before we leap," President Obama qualified at a press conference in Mexico City.

But the country still hasn’t developed the technology to weaponize the long-range missile, according to the assessment.

A spokesman for the IG's office said this marks the first time the office will review a review board's process.

Sen. Bob Corker wants an explanation from President Obama for payments that were reportedly sent to Afghan officials.

The State Department on Thursday lifted a visa ban on Burma's military and government officials as part of the Obama administration's efforts to encourage the country's transition to democracy.

The 1996 ban targeted “persons who formulate, implement, or benefit from policies that impede Burma’s transition to democracy, and the immediate family members of such persons.” Burma, also known as Myanmar, remains subject to other travel sanctions under the Immigration and Naturalization Act, the 2008 JADE Act targeting regime leaders and President Obama's Executive Order 13619 of last July that targets human-rights abusers and people who threaten peace.

“This termination, effective immediately, is consistent with the Administration’s calibrated approach to strengthen and encourage further reform while holding Burma to its commitments on human rights and democratization,” the State Department said.

“You look and rethink all options. It doesn’t mean you do, or you will,” the Defense secretary said.

White House press secretary Jay Carney said Thursday that the White House was working to confirm that North Korea had sentenced an American citizen to 15 years of hard labor.

"We've seen those reports ... and we're working with our protecting power, the Embassy of Sweden in Pyongyang, to confirm them," Carney told reporters aboard Air Force One.

The Associated Press reported Thursday that Kenneth Bae of Washington state had been sentenced for "committing hostile acts" against North Korea. South Korean human rights campaigners say Bae may have angered the regime by taking photographs of impoverished children or public executions during his travels in the country.

The State Department on Thursday asked that North Korea grant amnesty to an American citizen sentenced to 15 years of hard labor.

Kenneth Bae, a tour operator from Washington state who has visited the country several times, was arrested last year near the border with China. North Korea has accused him of unspecified “hostile acts” against the state in a case that's largely seen as an effort to extract food aid and other concessions from the United States.

“There is no greater priority for us than the welfare and safety of U.S. citizens abroad, and we urge the [North Korean] authorities to grant Mr. Bae amnesty and immediate release,” State Department spokesman Patrick Ventrell said Thursday. “We've had deep concerns about the transparency and due process across the breadth of the North Korean legal system.”
