“I deeply regret the sloppiness involved, but I had no intention of withholding documents from the commission, and to the contrary, to my knowledge, every document requested by the commission from the Clinton administration was produced,” Berger said in a statement to the AP.

When asked, Berger said he returned some of the classified documents, which he found in his office, and all of the handwritten notes he had taken from the secure room, but said he could not locate two or three copies of the highly classified millennium terror report.

“When I was informed by the Archives that there were documents missing, I immediately returned everything I had except for a few document that I apparently had accidentally discarded,” he said.

Berger and his lawyer said Monday night he knowingly removed handwritten notes he had taken from classified anti-terror documents he reviewed at the National Archives by sticking them in his jacket and pants.

“In the course of reviewing over several days thousands of pages of documents on behalf of the Clinton administration in connection with requests by the Sept. 11 commission, I inadvertently took a few documents from the Archives,” Berger said.

I inadvertently took a few documents from the Archives … by sticking them in [my] jacket and pants…

Some drafts of a sensitive after-action report on the Clinton administration’s handling of al-Qaida terror threats during the December 1999 millennium celebration are still missing.

Berger served as Clinton’s national security adviser for all of the president’s second term and most recently has been informally advising Democratic presidential candidate John Kerry.
