President Bush signed a secret order in 2002 authorizing the National Security Agency to eavesdrop on U.S. citizens and foreign nationals in the United States, despite previous legal prohibitions against such domestic spying, sources with knowledge of the program said last night.
The super-secretive NSA, which has generally been barred from domestic spying except in narrow circumstances involving foreign nationals, has monitored the e-mail, telephone calls and other communications of hundreds, and perhaps thousands, of people under the program, the New York Times disclosed last night.
The aim of the program was to rapidly monitor the phone calls and other communications of people in the United States believed to have contact with suspected associates of al Qaeda and other terrorist groups overseas, according to two former senior administration officials. Authorities, including a former NSA director, Gen. Michael V. Hayden, were worried that vital information could be lost in the time it took to secure a warrant from a special surveillance court, sources said.
