Members of Congress will meet with the CIA today to urge the agency to release documents that could shed light on the activities of Nazis who worked for the intelligence agency during the Cold War.

Under a 1998 law requiring full disclosure of classified records related to Nazi war criminals, more than 8 million documents have already been made public by the CIA, the Justice and Defense departments, the FBI, and the National Security Council. The figure includes 1.2 million documents from the CIA, all of which are available at the National Archives in Washington.

However, some members of a working group created to oversee the records’ declassification say the CIA has flouted the law by withholding thousands of related documents. The CIA is the only agency that has not fully complied with the Nazi War Crimes Disclosure Act of 1998, said a member of the Nazi War Crimes Interagency Working Group, Elizabeth Holtzman.

“They don’t want to give us everything about Nazi war criminals, especially those who worked for them,” Ms. Holtzman, the former congresswoman who was also a Kings County district attorney and New York City comptroller, told reporters yesterday. “We need to know about those henchmen and our government’s relationship with them.”

The other two private citizens in the group, Washington lawyer Richard Ben-Veniste and former federal prosecutor Thomas Baer, have also urged the CIA to fully disclose all information about Nazis – not just those involved in war crimes, a distinction they say the CIA has used to justify withholding information.

The group’s other members, who include representatives of the CIA, the FBI, the Defense Department, and other government agencies, have not commented on the dispute.

The CIA, which was established after World War II, acknowledges it recruited former Nazis to help gather intelligence during the Cold War, but says it has not withheld any files dealing with the commission of war crimes, said a CIA spokesman, Paul Gimigliano.

The meeting on Capitol Hill today, which is being hosted by the war-crime law’s bipartisan sponsors, Rep. Carolyn Maloney of New York and a Republican senator from Ohio, Michael DeWine, will be the first aimed at persuading the CIA to disclose documents the working group says it needs to complete its mandate. The group’s tenure expires at the end of March, but its members say they will ask Congress for an extension until they receive the CIA’s documents. Historians used the documents already disclosed to publish a book last year entitled “U.S. Intelligence and the Nazis,” which showed that associates of Adolf Eichmann, the Nazi party member who led Hitler’s genocidal campaign against Jews, worked for the CIA after the war.

Jewish community leaders have said full disclosure of all documents detailing the American government’s use of former Nazis in intelligence-gathering would bring closure for relatives of those who perished during the Holocaust, as well as a complete accounting of history.

“It’s so important to ensure the accuracy of history,” said the chief executive officer of the Jewish Community Relations Council of New York, Rabbi Michael Miller. “That is the imperative that is driving the resolution of this issue.”
