David Edward Bonior (born June 6, 1945) is an American politician from the U.S. state of Michigan. First elected to the U.S. House of Representatives in 1976, Bonior served as Democratic whip in the House from 1991 to 2002, during which time Democrats were in both the majority (1991-1995) and minority (1995-2002), making Bonior the third and second highest-ranking Democrat in the House, respectively. During his tenure in office, Bonior was the public face of Democratic opposition to the North American Free Trade Agreement (NAFTA), and was known for his tenacity in opposing Republican Speaker of the House Newt Gingrich, against whom Bonior filed more than seventy-five ethics charges.
Bonior was born in Detroit, Michigan, and graduated from Notre Dame High School in Harper Woods, Michigan, in 1963 where he excelled in sports. He received a B.A. from the University of Iowa, where he also played football and was a member of Sigma Alpha Epsilon, in 1967. He received a M.A. from Chapman College in Orange, California in 1972. He served in the United States Air Force during the peak of the Vietnam War, from 1968 to 1972. However, he did not serve in Vietnam.
Bonior was a Democratic member of the Michigan State House of Representatives from 1973 to 1976. In 1976, he was elected to the U.S. House of Representatives from Michigan's 12th District (based in Macomb County) for the 95th and to the twelve succeeding Congresses, serving from January 3, 1977 to January 3, 2003. His district was renumbered as the 10th in 1993, after Michigan lost a House seat as a result of the 1990 United States Census.
