Rand Paul, the junior Senator from Kentucky has kept his promise and filed a class action lawsuit against President Barack Obama and other administration officials for the National Security Agency (NSA) program that collected millions of Americans’ phone and other records.

“I am filing a lawsuit against President Barack Obama because he has publicly refused to stop a clear and continuing violation of the 4th Amendment,” Paul said in a statement from his political action committee. “The Bill of Rights protects all citizens from general warrants.” Tea Party organization, Freedomworks is the co-plaintiff in the law suit.

FreedomWorks president Matt Kibbe said at the press conference that he thinks “this is probably one of the most important things that my organization has ever participated in.”
