WASHINGTON (AP) -- A leading Republican senator on Tuesday described controversial U.S. spy programs as looking far deeper into Americans' phone records than the Obama administration has been willing to admit, fueling new privacy concerns as Congress sought to defend the surveillance systems.
Sen. Lindsey Graham, R-SC., says the U.S. intelligence surveillance of phone records allows analysts to monitor U.S. phone records for a pattern of calls, even if those numbers have no known connection to terrorism.
Graham says the National Security Agency then matches phone numbers against known terrorists. Graham helped draft the surveillance law that governs the surveillance program.
The office of the director of national intelligence declined to comment.
