John Edward "Jack" Cunningham III (born March 27, 1931) is an American former politician who served as a former RepublicanU.S. Representative from Washington's seventh district for one term from 1977 to 1979.
Cunningham was elected as a Republican to the seventh district vacancy in a special election when U.S. Representative Brock Adams resigned to become Secretary of Transportation. However his victory in this liberal district was more the result of confusion with Adams's resignation.[citation needed] Cunningham lost reelection in 1978, and served from May 17, 1977 – January 3, 1979.
