President Obama, responding to mounting criticism of his Justice Department's seizure of reporter records, said for the first time Thursday that the administration would be reviewing its guidelines in response to the controversy. Obama said he's "troubled" by the developments and that journalists should not be "at legal risk" for doing their jobs. 

Until now, administration officials have responded to the blowback by speaking generally about the importance of balancing national security -- and their ability to prosecute high-profile leaks -- with freedom of the press.

WASHINGTON –  The Obama administration acknowledged for the first time Wednesday that four American citizens have been killed in drone strikes since 2009 in Pakistan and Yemen. The disclosure to Congress comes on the eve of a major national security speech by President Barack Obama.

In conducting U.S. counterterrorism operations against al-Qaida and its associated forces, the government has targeted and killed one American citizen, Anwar al-Awlaki, and is aware of the killing by U.S. drones of three others, Attorney General Eric Holder said in a letter to Senate Judiciary Committee Chairman Patrick Leahy.
