The president’s nominee for Director of the CIA John Brennan was approved by the Senate Intelligence Committee Tuesday (12-3) after the White House released additional information to Senators on both the Benghazi attacks and the administration’s legal justification for drone strikes. Brennan’s nomination in January was met with immediate criticism from civil libertarians and those who disapprove of President Obama’s use of drones and targeted killings of American ciritzens, which Brennan is thought to have spearheaded during his time as a counterterrorism advisor in the White House over the last four years. The growing frustration and criticism of the Obama drone policy and unauthorized assassinations reached a new high Wednesday, with a filibuster of the Brennan nomination by Senator Rand Paul, joined by Republican Senators Mike Lee, Ted Cruz and Jerry Moran, as well as Democrat Senator Ron Wyden.

On Tuesday, Paul received a letter from Attorney General Eric Holder attempting to answer the Senator’s question if the president has the authority to kill an American on American soil without a trial. While recognizing that the situation presented by Paul is highly unlikely, Holder wrote “It is possible, I suppose, to imagine an extraordinary circumstance in which it would be necessary and appropriate under the Constitution and applicable laws of the United States for the President to authorize the military to use lethal force within the territory of the United State.”

Paul described Holder’s answer in a statement Wednesday as “frightening.” 

“I will speak until I can no longer speak,” Paul said Wednesday when beginning his filibuster of Brennan. “All I’m asking of the president is that he says in public that he’s not in favor of summarily executing people,” Paul went on to say.

“Real News” Wednesday opened up with debate on Brennan’s nomination, Holder’s letter to Paul and today’s filibuster. Watch a clip below:
