Senator Rand Paul (R-KY) has launched a class-action lawsuit against the the Obama administration for its bulk collection of American phone records. In a press release, Paul said Obama has refused to stop a clear and continuing violation of the Fourth Amendment, leading him to file suit on behalf of American citizens. The suit is also backed by Matt Kibbe, president of major conservative advocacy group FreedomWorks. Paul is a longtime critic of NSA surveillance and the Obama administrations covert military program in general, holding a 13-hour filibuster in early 2013 to protest American drone strike policies.
