The president may be removed from office and never allowed to hold a government position again if he is found guilty. Our 17th president, Andrew Johnson, was impeached while in office. Thirty-five senators found him guilty -- just one vote short of the two-thirds vote necessary to convict him. President Richard Nixon resigned from office rather than face impeachment charges in the Watergate scandal in 1974. President Bill Clinton became the second president to be impeached by the House in 1998. Later, the Senate found him not guilty.
