Clinton national security adviser Samuel Berger admitted in 2005 to taking five copies of a highly classified document from the archives and Davis, the outgoing chairman of the House Government Reform Committee, pledged Thursday to continue the investigation, The Washington Post reported.
He said that Berger's actions "suggest an intentional effort to keep critical information away from the 9/11 commission and the American public." Davis told the newspaper that his staff would publish its final report in January.
The document in question is a classified study from the Clinton administration titled "Millennium Alert After Action Review." It contains information about a series of terrorist threats in 1999 and was distributed to approximately 15 high-level officials.
Berger's removal of the documents came while he was preparing to testify before the 9/11 commission, raising speculation about a coverup of counter-terrorism measures during the Clinton administration.
