NSA Gave Other U.S. Agencies Information From Surveillance

Fruit of Eavesdropping Was Processed and Cross-Checked With Databases

Information captured by the National Security Agency's secret eavesdropping on communications between the United States and overseas has been passed on to other government agencies, which cross-check the information with tips and information collected in other databases, current and former administration officials said.

The NSA has turned such information over to the Defense Intelligence Agency (DIA) and to other government entities, said three current and former senior administration officials, although it could not be determined which agencies received what types of information. Information from intercepts -- which typically includes records of telephone or e-mail communications -- would be made available by request to agencies that are allowed to have it, including the FBI, DIA, CIA and Department of Homeland Security, one former official said.



At least one of those organizations, the DIA, has used NSA information as the basis for carrying out surveillance of people in the country suspected of posing a threat, according to two sources. A DIA spokesman said the agency does not conduct such domestic surveillance but would not comment further. Spokesmen for the FBI, the CIA and the director of national intelligence, John D. Negroponte, declined to comment on the use of NSA data.

Since the revelation last month that President Bush had authorized the NSA to intercept communications inside the United States, public concern has focused primarily on the legality of the NSA eavesdropping. Less attention has been paid to, and little is known about, how the NSA's information may have been used by other government agencies to investigate American citizens or to cross-check with other databases. In the 1960s and 1970s, the military used NSA intercepts to maintain files on U.S. peace activists, revelations of which prompted Congress to restrict the NSA from intercepting communications of Americans.



Today's NSA intercepts yield two broad categories of information, said a former administration official familiar with the program: "content," which would include transcripts of a phone call or e-mail, and "non-content," which would be records showing, for example, who in the United States was called by, or was calling, a number in another country thought to have a connection to a terrorist group. At the same time, NSA tries to limit identifying the names of Americans involved.

"NSA can make either type of information available to other [intelligence] agencies where relevant, but with appropriate masking of its origin," meaning that the source of the information and method of getting it would be concealed, the former official said.
