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 9. 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.
