About John Ensign
John Eric Ensign is an American veterinarian and former politician who served as a United States senator from Nevada from 2001 until his resignation in 2011 amid a Senate Ethics Committee investigation into his attempts to hide an extramarital affair. A member of the Republican Party, Ensign previously represented Nevada's 1st congressional district in the House of Representatives from 1995 to 1999, the only Republican to represent the district. Following his resignation from the Senate, Ensign returned to Nevada and resumed his career as a veterinarian. In 1994, Ensign won the Republican nomination for Nevada's 1st congressional district, based in Las Vegas. Ensign won the election by 1,400 votes and was reelected in 1996 by seven points, although Democratic presidential candidate Bill Clinton carried the district by a large margin that year. Ensign won a Senate seat on his second try in 2000, defeating Democratic opponent Ed Bernstein by a 55%–40% margin, to succeed the retiring Democratic incumbent, Richard H. Ensign, a gaming industry executive; he formally adopted young John, who considers him his "real father." The senior Ensign later became chairman of the board of directors of Mandalay Resort Group.
