Peter Vidmar is the winner of two Olympic gymnastics gold medals in 1984 in Los Angeles who was first named chef de mission for the 2012 U.S. Olympic team but then he was forced to resign abruptly after the gay lobby found out that he donated $2,000 for the successful 2008 Proposition 8 ballot initiative in California defining marriage as between a man and a woman. As of 2011, Vidmar was chairman of the board of USA Gymnastics and has served on the President's Council for Physical Fitness.

The proposition overturned a California Supreme Court ruling that permitted same-sex marriage. "Olympic gold medalist joins Rancho Prop 8 demonstration," said The Orange County Register on Oct. 30, 2008, in which it quoted Vidmar as saying, "It's good for our society to have a traditional definition of marriage."”
