President Bill Clinton made what is perhaps the most infamous confession of sexual impropriety by a U.S. politician in history. In January 1998, soon after reports surfaced that Clinton had an affair with White House intern Monica Lewinsky, he emphatically said, "I did not have sexual relations with that woman." By August, as a congressional investigation grilled Lewinsky and she turned over a DNA-stained dress, Clinton made a televised address to the nation, and admitted to an "improper physical relationship" with her. The House of Representatives voted to impeach the president for perjury, but he was subsequently acquitted.
