Susan McDougal

Her refusal to answer "three questions" for a grand jury, on whether President Bill Clinton lied in his testimony during her Whitewater trial, led her to receive a jail sentence of 18 months for contempt of court. That made up most of the total 22 months she spent incarcerated.
She received a full pardon from Clinton in the final hours of his presidency in January 2001. Provided by Wikipedia
