Robert Linlithgow Livingston Jr. (born April 30, 1943) is an American lobbyist and politician who served as a U.S. Representative from Louisiana from 1977 to 1999. A Republican, he was chosen as Newt Gingrich’s successor as Speaker of the U.S. House of Representatives, a position he declined following revelations of an extramarital affair. He served as a U.S. Representative from Louisiana from 1977 to 1999 and as the Chairman of the Appropriations Committee from 1995–1999. During his final years in congress, Livingston was a strong supporter of Bill Clinton’s impeachment. He is currently a Washington, D.C.-based lobbyist. Livingston’s memoir, The Windmill Chaser: Triumphs and Less in American Politics, was published in September 2018.
