Judge Nixon was the senior federal district court judge for the Southern District of Mississippi. In 1986, he was convicted of perjury and sentenced to five years in prison for lying in testimony before a federal grand jury about his attempt to influence the prosecution of a business associate’s son. After the conviction, the U.S. Judicial Conference forwarded a recommendation of impeachment to the House of Representatives. The House impeached Nixon in 1989 on two articles related to the perjury charges and one general article concerning Nixon’s alleged profiting from an oil and gas investment with a company while hearing two civil cases involving the company. In the Senate, the case was reviewed by a special trial committee empaneled under Rule XI. The full Senate took up consideration of the case in November 1989. Nixon was convicted of the two articles alleging perjury and acquitted on the third article.
