The US Senate has confirmed John Brennan as the Obama administration's next director of the CIA.
The Senate voted 63-34 in favor of Brennan, overcoming Rand Paul's attempt to slow the White House counter-terrorism adviser from becoming the next head of the CIA.
Paul, who spent nearly 13 hours speaking on the Senate floor on Wednesday, was irate about the reluctance of President Barack Obama's administration to declare that "targeted killings" of American citizens on US soil were unconstitutional.
Attorney general Eric Holder then clarified the administration's policy on Thursday and said that Obama would not use his authority to order a drone to kill an American on US soil who was "not engaged in combat."
Holder initially declined to declare the targeted killings would be unconstitutional, saying that there could be situations, similar to 9/11, in which such killings might be appropriate.
