In April 2005, Berger plead guilty to a misdemeanor charge of unauthorized removal and retention of classified material from the National Archives in Washington. In 1999, Berger was criticized for failing to promptly inform President Clinton of his knowledge that the People's Republic of China had managed to acquire the designs of a number of U.S. nuclear warheads. Berger was originally briefed of the espionage by the United States Department of Energy (DOE) in April 1996, but did not inform the president until July 1997. In November 1997, Berger paid a $23,000 civil penalty to settle conflict of interest allegations stemming from his failure to sell his stock of Amoco Corporation as ordered by the White House.
