Robert Linlithgow Livingston, Jr., known as Bob Livingston (born 1943 in Colorado Springs, Colorado), is a Republican former member of the United States House of Representatives from Louisiana's First Congressional District, based largely in the New Orleans suburbs. In August 1977, Livingston won a special election for the U. S. House seat by defeating the Democratic State Representative Ron Faucheux. Livingston succeeded Richard Alvin Tonry (1935-2012), the last Democrat to hold the First District seat. Livingston resigned from the House in the spring of 1999 after nearly twenty-two years of service, just a few months after he had won his last term in November 1998.
In 1987, Congressman Livingston ran a weak third in the race for governor of Louisiana. Victory went to then Democrat U.S. Representative Buddy Roemer, who led the nonpartisan blanket primary. The second-place candidate, third-term Governor Edwin Edwards, withdrew from what would have been the general election. Roemer subsequently was defeated for reelection in 1991, when Edwards reclaimed the governorship in a contested runoff with then State Representative David Duke of Jefferson Parish.
Livingston resigned from Congress during the time of the impeachment of U.S. President Bill Clinton after it was revealed that Livingston was having an extra-marital affair. The Speaker's position then went to J. Dennis Hastert of Illinois. Livingston reconciled with his wife, the former Bonnie Robichaux, a niece of the late Democratic U.S. Senator Allen J. Ellender of Louisiana. The Livingstons' son, Richard, was killed in 2006 by a live wire while he was trimming a tree.
