Which US President was impeached in 1998?

Bill Clinton, the 42nd president of the United States, was impeached by the United States House of Representatives of the 105th United States Congress on December 19, 1998, for "high crimes and misdemeanors". The House adopted two articles of impeachment against Clinton, with the specific charges against Clinton being lying under oath and obstruction of justice. The approved articles of impeachment would be submitted to the United States Senate on January 7, 1999. A trial in the Senate then began, with Chief Justice William Rehnquist presiding. On February 12, Clinton was acquitted on both counts as neither received the necessary two-thirds majority vote of the senators present for conviction and removal from office—in this instance 67.
