Marco Rubio Signs on to Filibuster Harry Reid's Gun-Control Bill

Sen. Marco Rubio, R-Fla., has signed on to Sen. Rand Paul's move to filibuster an upcoming gun-control bill that is expected to land on the Senate floor this week.

In a second letter to Senate Majority Leader Harry Reid, obtained by Politico, the Kentucky Republican was backed by a dozen other GOP senators, including Rubio. Sens. Ted Cruz of Texas, Mike Lee of Utah, and National Republican Senatorial Committee Chairman Jerry Moran of Kansas are among other signatories.

The gun bill would expand background checks and attempt to rein in gun trafficking across state lines. But, the GOP senators' letter states they intend to oppose any legislation that would infringe on the American peoples constitutional right to bear arms, or their ability to exercise this right without being subjected to government surveillance, reports Politico.

Paul's 13-hour March filibuster that held up the nomination of CIA Director John Brennan shows he has what it takes to mount a successful stand on the Senate floor.
