FILE - In this Jan. 31, 2008, file photo President Bush waves after signing a 15-day extension of the Protect America Act after a speech in Las Vegas. Sternly prodding Congress,  Bush told lawmakers they were jeopardizing the nation's safety by failing to lock in the government eavesdropping law. When the Protect America Act made warrantless wiretapping legal, lawyers and executives at major technology companies knew what was about to happen. They didn't know that its passage gave birth to a top-secret NSA program, officially labeled US-98XN. It was known as Prism. (AP Photo/Jae C. Hong, File)
