(Roll Call) After a 13-hour filibuster led by Sen. Rand Paul over drone strike policies within U.S. borders, senators took procedural steps early Thursday to advance the nomination of John O. Brennan to be CIA director.

At 12:40 a.m., the Kentucky Republican finally yielded the floor after a long day in which he and other GOP senators argued the White House should rule out the use of drone strikes on American soil.

“I just hope this won’t be swept under the rug,” Paul said. “I would go another 12 hours, but I’ve discovered there are some limits to filibustering, and I have to take care of one those in just a few minutes here.”
