Sen. Rand Paul, R-Ky., walks to a waiting vehicle as he leaves the Capitol after his filibuster of the nomination of John Brennan to be CIA director on Capitol Hill in Washington, early Thursday, March 7, 2013. Senate Democrats pushed Wednesday for speedy confirmation of John Brennan’s nomination to be CIA director but ran into a snag after Paul began a lengthy speech over the legality of potential drone strikes on U.S. soil. But Paul stalled the chamber to start what he called a filibuster of Brennan’s nomination. (AP Photo/Charles Dharapak)
