WASHINGTON (AP) - Almost 13 hours after he began speaking, Sen. Rand Paul ended his day-long filibuster at 12:38 a.m. today because he had to go to the bathroom.
"I would go for another 12 hours to try to break Strom Thurmond's record, but I've discovered that there are some limits to filibustering, and I'm going to have to go take care of one of those in a few minutes here," Paul said.
The Kentucky Republican stalled a confirmation vote on CIA Director nominee John Brennan.
Paul, known for his libertarian leanings, has sharply questioned the Obama administration's use of drones against American citizens overseas. And he vowed to speak until he received more answers from the government about its policies.
Brennan is considered one of the main architects of the drone program.
Paul kept a sense of humor about his marathon talk-fest.
Former Sen. Thurmond of South Carolina holds the record for filibustering. He famously filibustered for 24 hours and 18 minutes against the Civil Rights Act of 1957.
