NSA has massive database of Americans' phone calls

By Leslie Cauley, USA TODAY
The National Security Agency has been secretly collecting the phone call records of tens of millions of Americans, using data provided by AT&T, Verizon and BellSouth, people with direct knowledge of the arrangement told USA TODAY.
The NSA program reaches into homes and businesses across the nation by amassing information about the calls of ordinary Americans — most of whom aren't suspected of any crime. This program does not involve the NSA listening to or recording conversations. But the spy agency is using the data to analyze calling patterns in an effort to detect terrorist activity, sources said in separate interviews............

.........The White House would not discuss the domestic call-tracking program. "There is no domestic surveillance without court approval," said Dana Perino, deputy press secretary, referring to actual eavesdropping.
She added that all national intelligence activities undertaken by the federal government "are lawful, necessary and required for the pursuit of al-Qaeda and affiliated terrorists." All government-sponsored intelligence activities "are carefully reviewed and monitored," Perino said. She also noted that "all appropriate members of Congress have been briefed on the intelligence efforts of the United States." ............
