George Mitchell served as US Special Envoy for Middle East Peace from January 2009 to May 2011. Prior to that he had a distinguished career in public service. He was appointed to the United States Senate in 1980 to complete the unexpired term of Senator Edmund S. Muskie, who resigned to become Secretary of State. He was elected to a full term in the Senate in 1982 in a stunning come-from-behind victory. In 1988, he was reelected with 81 percent of the vote, the largest margin in Maine history. He served as Senate Majority Leader from 1989 to 1995. During his tenure in the Senate, it was said "there is not a man, woman or child in the Capitol who does not trust George Mitchell." For six consecutive years he was voted "the most respected member" of the Senate by a bipartisan group of senior congressional aides. In 1995, he served as a Special Advisor to President William J. Clinton on Ireland, and from 1996 to 2000 he served as the Independent Chairman of the Northern Ireland Peace Talks. Under his leadership, the Good Friday Agreement, an historic accord ending decades of conflict, was agreed to by the governments of Ireland and the United Kingdom and the political parties of Northern Ireland. For his service in Northern Ireland Senator Mitchell received numerous awards and honors, including the Presidential Medal of Freedom, the highest civilian honor given by the U.S. government; the Philadelphia Liberty Medal; the Truman Institute Peace Prize; and the UNESCO Peace Prize. In 2000 and 2001, at the request of President Clinton, Prime Minister Ehud Barak, and Chairman Yasser Arafat, Senator Mitchell served as Chairman of an International Fact-Finding Committee on violence in the Middle East. The Committee's recommendation, widely known as The Mitchell Report, was endorsed by the Bush Administration, the European Union and by many other governments. In 2006 and 2007 he led the investigation into the use of performance-enhancing drugs in Major League Baseball. He also served as Chairman of the Special Commission Investigating Allegations of Impropriety in the Bidding Process for the Olympic Games and was the Independent Overseer of the American Red Cross Liberty Fund, which provided relief for September 11 attack victims and their families. Senator Mitchell served as Chairman of the global board of the law firm DLA Piper; Chairman of the board of directors of The Walt Disney Company; a member of the board of the Boston Red Sox; and a director of several companies, including Federal Express, Xerox, Staples, Unilever and Starwood Hotels and Resorts. He also served for ten years as the Chancellor of Queen’s University of Northern Ireland; as President of the Economic Club of Washington; and as Chairman of the International Crisis Group.
