As anticipated [JURIST report], former US National Security Advisor Sandy Berger [Wikipedia profile] pleaded guilty Friday to illegally taking and destroying classified documents from the National Archives [official website]. The former Clinton Administration official acknowledged that he intentionally took and deliberately destroyed three copies of the same document dealing with terror threats during the 2000 millennium celebration and then lied about it to Archives staff when they told him documents were missing. As part of his sentencing agreement, Berger surrendered his security clearance and agreed to cooperate with the government concerning his activities at the National Archives.
