Thomas Slade Gorton III (born January 8, 1928) is an American politician. A Republican, he was a U.S. Senator from Washington state from 1981 to 1987, and from 1989 to 2001. He held both of the state's Senate seats in his career and was narrowly defeated for reelection twice as an incumbent: in 1986 by Brock Adams, and in 2000 by Maria Cantwell after a recount. Gorton was twice both senior Senator (1983–87, 1993–2001) and junior Senator (1981–83, 1989–93). As of 2020, he is the last Republican to have been a U.S. Senator from Washington.
Gorton was born in Chicago, Illinois, brother to Nathaniel M. Gorton, and served in the United States Army from 1945 until 1946. He then attended and graduated from Dartmouth College. He graduated from Columbia Law School, and served in the United States Air Force from 1953 until 1956, continuing to serve in the Air Force reserves until 1980 when he retired as a Colonel. Meanwhile, he practiced law, and entered politics in 1958, being elected to the state legislature of Washington, in which he served from 1959 until 1969, becoming one of the highest-ranking members. He was then Attorney General of Washington from 1969 until he entered the United States Senate in 1981. During his three terms as Attorney General, Gorton was recognized for taking the unusual step of appearing personally to argue the state's positions before the Supreme Court of the United States and for prevailing in those efforts.
U.S. Senate campaigns
In 1980 he defeated longtime incumbent U.S. Senator and state legend Warren Magnuson by a 54% to 46% margin.
In the Senate, Gorton had a moderate-to-conservative voting record, and was derided for what some perceived as strong hostility towards Indian tribes. His reelection strategy centered on running up high vote totals in areas outside of left-leaning King County (home to Seattle).
In 1994 he repeated the process, defeating then-King County Councilman Ron Sims by 56% to 44%. He was an influential member of the Armed Services Committee as he was the only member of the committee during his tenure to have reached a senior command rank in the uniformed services (USAF).
He campaigned in Oregon for Gordon Smith and his successful 1996 Senate run.
In 1999, Gorton was among ten Republican Senators who voted against the charge of perjury during Clinton's impeachment, although he voted for Clinton's conviction on the charge of obstruction of justice.
Twice during his tenure in the Senate, Gorton sat at the Candy Desk.
In 2002, Gorton became a member of the National Commission on Terrorist Attacks Upon the United States (popularly known as the "9/11 Commission") and the commission issued its final report in 2004. 
In 2005, Gorton became the Chairman of the center-right Constitutional Law PAC, a political action committee formed to help elect candidates to the Washington State Supreme Court and Court of Appeals.
Gorton is an Advisory Board member for the Partnership for a Secure America, a not-for-profit organization dedicated to recreating the bipartisan center in American national security and foreign policy. Gorton currently serves as a Senior Fellow at the Bipartisan Policy Center.
Gorton represented the city of Seattle in a lawsuit against Clay Bennett to prevent the relocation of the Seattle SuperSonics basketball franchise, in accordance to a contract that would keep the team in KeyArena until 2010. The city reached a settlement with Bennett, allowing him to move the team to Oklahoma City for $45 million with the possibility for another $30 million.
In 2010, the National Bureau of Asian Research founded the Slade Gorton International Policy Center. The Gorton Center is a policy research center, with three focus areas: policy research, fellowship and internship programs, and the Gorton History Program (archives). In 2013 the Gorton Center was the secretariat for the ‘Commission on The Theft of American Intellectual Property’, in which Gorton was a commissioner. Gorton is also a Counselor at the National Bureau of Asian Research.
Gorton is currently Of Counsel at K&L Gates LLP.
