A report to Congress reveals details on how U.S. intelligence officials used and protected some Nazi Gestapo agents after World War II. The report was authored by historians hired by the U.S. National Archives and Records Administration. The report draws from an unprecedented trove of records on clandestine operations that the CIA was persuaded to declassify and from previously inaccessible Army intelligence files. The CIA records give us a much better picture of the movements of Nazi war criminals in the postwar period. The Army records are voluminous, and will be keeping people busy for many years," said Richard Breitman, of the American University in Washington, D.C., who co-authored the report with Norman J.W. Goda, of the University of Florida. The records were made available under the Nazi War Crimes Disclosure Act of 1998. Nazi hunters and lawmakers have long raised questions about what U.S. government knew and its involvement with war criminals during the Cold War. The Nazi War Crimes Disclosure Act has so far resulted in more than 8 million documents being declassified; a landmark 2005 book on U.S. Intelligence and the Nazis in part authored by Breitman and Goda; and a final report to Congress.
