He had no apology, egyptian people, a.Q., Meaning al qaeda, bob gates, the former secretary of defense, effective and then i don't know what the other two words were saying. today, we saw a picture of it online. What happened backstage when you talked to them? Reporter: When we went back and saw vice president biden, it happened to be right at the time when he was getting a call from president obama, congratulating him on his debate and one of the things paul ryan said to me is, he said, boy, I really -- it's great.
