Sen. Rand Paul, R-Ky., intends to file a class action lawsuit challenging the constitutionality of a National Security Agency (NSA) program that collects phone records and other data from internet companies, according to documents leaked to the press by a whistleblower.

“I’m going to be seeing if I can challenge this at the Supreme Court level,” Paul, a libertarian-leaning Republican who made news earlier this year for a talking filibuster in protest of the drone strike program, told Fox News’ Chris Wallace. “I’m going to be asking all the Internet providers and all of the phone companies, ask your customers to join me in a class action lawsuit. If we get 10 million Americans saying we don’t want our phone records looked at then somebody will wake up and say things will change in Washington.”

Wallace asked Paul to respond to the idea that “In Rand Paul’s world, you have almost no defenses against terrorists,” as Sen. Lindsey Graham, R-S.C., claimed.

“[T]hat’s an unfair characterization,” Paul replied. “I want to go after terrorists as much as anyone. For example, we are looking through so much data that I think it makes our fight against terrorism worse. The Tsarnaev boy, one of the Boston marathon bombers, we didn’t know that he went back to Chechnya because we’re not doing enough targeted analysis.”
