Senator John McCain said in an interview Wednesday that he was uncertain how many houses he and his wife, Cindy, own. "I think I'll have my staff get to you," McCain told Politico in Las Cruces, N.M. "It's condominiums where I'll have them get to you."

The correct answer is at least four, located in Arizona, California and Virginia, according to his staff. Newsweek estimated this summer that the couple owns at least seven properties.
