Kentucky Sen. Rand Paul has a message for those who claim additional mass surveillance could have prevented the recent terror attacks in Paris, France, and a similar attack on U.S. soil.

"Bulls---," the Republican presidential hopeful told an estimated 200 students Thursday at George Washington University.

"There's already clamor to now demand more surveillance of the American people, [that] we would be safe if you would just give up more of your liberty," Paul said.

"When they stand up on television and say the tragedy in Paris means you need to give up your liberty [and] we need more phone surveillance, bulls---!" he added to overwhelming applause.
