Bush Defends Legality of Domestic Spy Program
By ERIC LICHTBLAU
Mr. Bush also emphasized that the program was "limited" in nature and designed to intercept communications from known associates of Al Qaeda to the United States. He said several times that the eavesdropping was "limited to calls from outside the United States to calls within the United States."
That assertion is at odds with press accounts and the public statements of his senior aides, who say that the authorization for the program requires that one end of a communication - either incoming or outgoing - be outside the United States. The White House, clarifying the president's remarks after his appearance, said later that either end of the communication can in fact be outside the United States.
Despite a prohibition on eavesdropping on phone calls or e-mail messages that are regarded as purely domestic,
The Times has reported that the N.S.A. has accidentally intercepted what are thought to be a small number of communications in which both ends were on American soil, due to technical confusion over what constitutes an "international" call.
Officials also say that the N.S.A., beyond actual eavesdropping on up to 500 phone numbers and e-mail addresses at any one time, has conducted much larger data-mining operations on vast volumes of communication within the United States to identify possible terror suspects.To accomplish this,
the agency has reached agreements with major American telecommunications companies to gain access to some of the country's biggest "switches," carrying phone and e-mail traffic into and out of the country.
