Clinton did not admit his affair until the annual White House prayer on September 11, 1998, in the presence of several ministers, priests and his wife, Hillary Clinton, in his "I have sinned" speech. The speech was hand-written by Clinton himself and was delivered on the day of publication of the first report by Independent Counsel Ken Starr, which threatened to impeach President Clinton in the grounds of perjury and his sexual affair with former White House intern, Monica Lewinsky. Clinton was eventually impeached, but not removed from office. Then-President of South Africa Nelson Mandela personally helped President Clinton during his impeachment hearing.
