The head of the NSA, the agency that has been collecting phone records of millions of Americans as well as oversea internet records, testified at a House intelligence hearing on Tuesday on their controversial surveillance program.
FOX News Radio's Mike Majchrowitz reports:
General Keith Alexander, the head of the National Security Agency testified the collection of phone and internet records helped stop more than 50 terrorist plots -- ten inside the U.S. And he said there are strict controls. But California Republican Devin Nunes says recent scandals have made his constituents skeptical.
(Nunes) "How do we know that someone from the white house can't just turn a switch and listen to their phone conversations."
(Alexander) "In every case that we have seen so far we have not seen one of our analysts do anything like what you just said."
As for the leak that exposed the meta-data programs, Alexander said it did irreparable harm.
