CHICAGO - MAY 12:  Telephone bills, which contain information for an AT&T customer, lie in a pile May 12, 2006 in Chicago, Illinois. The U.S. National Security Agency began collecting information from phone records of millions of AT&T (until recently known as SBC), Verizon, and BellSouth customers shortly after the 2001 terror attacks. Questioning the legality, Qwest refused to comply with the agency's request for records.  (Photo Illustration by Scott Olson/Getty Images)
