The impeachment trial of Bill Clinton, the 42nd president of the United States, began in the U.S. Senate on January 7, 1999, and concluded with his acquittal on February 12. After an inquiry between October and December 1998, President Clinton was impeached by the U.S. House of Representatives on December 19, 1998; the articles of impeachment charged him with perjury and obstruction of justice. It was the second impeachment trial of a U.S. president, preceded by that of Andrew Johnson.
The charges for which Clinton was impeached stemmed from a sexual harassment lawsuit filed against Clinton by Paula Jones. During pre-trial discovery in the lawsuit, Clinton gave testimony denying that he had engaged in a sexual relationship with White House intern Monica Lewinsky.
