Robert Linlithgow Livingston Jr. 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 to 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.

The speaker of the United States House of Representatives, commonly known as the speaker of the House, is the presiding officer of the United States House of Representatives. The office was established in 1789 by Article I, Section II, of the U.S. Constitution. By custom and House rules, the speaker is the political and parliamentary leader of the House and is simultaneously its presiding officer, de facto leader of the body's majority party, and the institution's administrative head. Speakers also perform various other administrative and procedural functions. Given these several roles and responsibilities, the speaker usually does not personally preside over debates—that duty is instead delegated to members of the House from the majority party—nor regularly participate in floor debates.
