COOPER: “You've been watching perhaps one of the most disgraceful performances by an American president at a summit in front of a Russian leader, certainly that I’ve ever seen. An extraordinary press conference. I’m back with CNN global affairs analyst Susan Glasser, CNN senior political analyst David Gergen, CNN chief international anchor Christiane Amanpour. Christiane, the president -- given the opportunity, asked by an American reporter who he trusted on the issue of Russian meddling, the U.S. intelligence community or Vladimir Putin, he blinked and he went to Hillary Clinton’s e-mail server. As to who he holds responsible, he says I hold both countries responsible. I think we are all to blame. We have a chance to do some great things; made no mention of Georgia, the shooting down of a Malaysian plane, Crimea and Ukraine, and election interference."
