"Let me say specifically about Susan Rice: She has done exemplary work. She has represented the U.S. and our interests in the U.N. with skill and professionalism and toughness and grace," said Mr. Obama. "If Senator McCain and Senator Graham and others want to go after somebody, they should go after me. And I'm happy to have that discussion with them. But for them to go after the U.N. ambassador? Who had nothing to do with Benghazi? And was simply making a presentation based on intelligence that she had received? To besmirch her reputation is outrageous."
