On Capitol Hill, Republican Senator John Ensign of Nevada has admitted he had an extramarital affair with a campaign staffer. Ensign was seen as a potential candidate for president in 2012. Ensign is a born-again Christian who was a member of the Promise Keepers, a male evangelical group that promotes marital fidelity. Ensign had once claimed he never met behind closed doors with women staff members and would not travel alone in a car with a woman who was not his wife. In 2007, Ensign urged Idaho Senator Larry Craig to resign after his arrest in a men’s bathroom for alleged lewd conduct.
