On Tuesday, the Senate undertook a cloture vote to end debate on a bill that would renew a controversial legal loophole that provides U.S. intelligence agencies with a means for the warrantless surveillance of American citizens. With 60 for and 38 against, the Senate voted in favor of cloture, a considerable blow to privacy advocates who have long pushed for reform.

A two-thirds majority cloture vote of 60 is necessary to end a Senate filibuster. The vote ran for over an hour, slowing down considerably as the final votes trickled in and eventually slowing to a halt at 58-38.
