Rand Paul Wouldn't Crack Top 5 In Filibuster Talking Hall Of Fame

On Wednesday, Sen. Rand Paul launched into a filibuster on the floor of the Senate, against John Brennan's nomination as CIA director. Paul, who said "I will speak until I can no longer speak," lasted for nearly 13 hours. It was an impressive length of time, but it didn't come close to Sen. Strom Thurmond's record-holding filibuster against the Civil Rights Act of 1957, which surpassed 24 hours. Melissa Block speaks with Senate historian Donald Ritchie about the colorful history of the talking filibuster.
