The New York Times revealed that Sen. John Ensign may have ignored laws when giving preferential treatment to a lobbyist that was the husband of his former lover. Fellow Republican Senator Jon Kyl refused to defend Ensign when given a chance Sunday. Sen. Barbara Boxer confirmed that the Senate Ethic Committee had opened an investigation into Ensign's actions. "We will look at all aspects of this case, as we do whenever there is a case before us, and try to get to the bottom of it as quickly as we can in fairness to all," Boxer told CNN's John King.
