He sure has had an interesting life.
He was the campaign manager for Senator Howard Baker's successful re-election campaign in 1972, which led to a close personal friendship with Baker, and he served as co-chief counsel to the Senate Watergate Committee in its investigation of the Watergate scandal, (1973–1974). There he asked the key question, "Mr. Butterfield, were you aware of the existence of any listening devices in the Oval Office of the President?"
In 1977, Thompson took on a Tennessee Parole Board case that ultimately toppled Tennessee Governor Ray Blanton from power on charges of selling pardons. The scandal became the subject of a book and a movie titled Marie (1985) in which Thompson played himself, supposedly because the producers were unable to find a professional actor who could play him plausibly. This film launched his acting career. Thompson would go on to appear as racist demagogue "Dr. Knox Pooley" in a story arc of the TV series Wiseguy (1988) and in numerous feature films, including The Hunt for Red October (1990), Cape Fear (1991), and In the Line of Fire (1993).
On November 8, 1994, Thompson was elected to the United States Senate to fill the unexpired portion of the term ending January 3, 1997, left vacant by the resignation of Al Gore, defeating six-term Democratic U.S. Representative Jim Cooper in a landslide which represented the most votes anyone had ever received for a statewide office in Tennessee history up to that point.
While in the Senate, he was chair of the Committee on Governmental Affairs from 1997 to January 3, 2001 which conducted investigations into allegations China attempted to influence American politics prior to the 1996 elections
After the sudden death of his daughter from unrelated events, he decided not to pursue re-election.
In the final months of his term, he joined the cast of the long-running NBC television series Law & Order, playing Arthur Branch. In doing so, he became the first serving U.S. Senator concurrently to hold a full-time television acting job; however, his first scenes as Branch were filmed during the Senate's August 2002 recess, so he missed no legislative time in order to act on television.
In 2005, he was given an informal position by President George W. Bush to help guide the nominated John Roberts to the confirmation through the United States Senate. In 2006, Thompson signed on with ABC News Radio, where he'll serve as a host, commentator, and fill in for Paul Harvey.[2]
There was speculation that Thompson would run for Governor of Tennessee in 2006, but he declined to run against the popular Governor Phil Bredesen.
As of March 2, 2007, Thompson was reportedly considering a run for President in 2008.
