The House voted Thursday morning to approve a bill that renews the National Security Agency's warrantless surveillance program, known as Section 702 of the Foreign Intelligence Surveillance Act, with a few small changes. The bill passed 256-164.

The bill now heads to the Senate, which is expected to take up the measure before the surveillance program expires on Jan. 19.

Paul previously threatened to filibuster “any long term extension of warrantless searches of American citizens.”

Last month Paul put a hold on one of Trump’s Justice Department appointees over concerns regarding the nominee’s views on surveillance.

The nominee, John Demers, had previously spoken favorably about Section 702 surveillance, which privacy hawks like Paul have argued provides a backdoor for authorities to surveil American citizens.
