Republican Kentucky Sen. Rand Paul tied up the Senate for 13 hours Wednesday as he filibustered a vote on the president's pick to head the CIA.
The old-fashioned filibuster allows a Senate member to keep the body from voting by holding the floor as long as he can keep speaking.
Paul was protesting U.S. policy regarding the use of unmanned drones. He said he wants written assurance they won't be used to kill American terror suspects in the United States.
The Kentucky lawmakers ended his talk at 1 a.m., long enough to delay the vote on John Brennan, who is expected to be confirmed today.
Was the filibuster successful? David Brody, CBN News Chief Political Correspondent, talks about that and more on Newswatch. Watch here.
