NBC says:

Pledging to speak "until I can no longer speak," Kentucky Republican Rand Paul on Wednesday launched a Senate floor filibuster of the nomination of John Brennan to be the next CIA director.

Brennan still could be confirmed as early as this afternoon, as Paul is speaking at length on the floor rather than objecting to a larger Republican agreement to allow a vote on Brennan's confirmation to go forward.

Paul objects to what he calls the Obama administration's lack of clarity over whether a suspected terrorist who is an American citizen can be targeted with a drone strike on American soil.

Every so often, Ron Paul would do or say something—protest the war in Iraq, for example, or complain about American imperialism—that would get liberals nodding their head in assent. Looks like Rand is following in his daddy's footsteps by taking a very public stand against misuse of drones, which many liberals find to be a repulsive Obama Administration policy. The important to thing to remember, though, is that 99% of Senator Paul's other policies are offensive and dumb. This is a case of a stopped clock being right, not a sign of improvement.
