Sandy Berger now admits that it was no "honest mistake" when he took classified documents from the National Archives.
The former Clinton national security adviser has pleaded guilty to taking the documents and cutting them up with scissors.
Berger told a federal judge in Washington that he intentionally took three copies of a document about terror threats, and destroyed them.
The documents deal with the government's anti-terror efforts during the 2000 millennium celebration.
Under a plea deal that the judge must accept, Berger will serve no jail time for the misdemeanor. He's to pay a ten-thousand-dollar fine and lose his security clearance for three years. His sentencing is scheduled for July 8.
