Martha raddatz is with us now. It is great to see you. Reporter: It's great to see you, diane. And it's great to have this behind us. Put us in your chair. What could you see that we couldn't see from home? Reporter: I think one of the things about being at that table, it is so intimate, so, when joe biden is smiling or when joe biden is raising his voice a bit, it's really in your face, it was really in paul ryan's face. They were watching the clock so carefully, those opening statements of two minutes, with each question. They would always fill those two minutes exactly. They were both taking notes. This is what vice president biden wrote down. 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. I've been looking at a lot of tapes of you for a long time and you've been to afghanistan a lot of times. Do you know? Reporter: I don't. I used to keep track in iraq. I can tell you, that was 21 times. But I think to the region, pakistan, afghanistan, I've lost track, but it's definitely dozens of times. All right, well, martha raddatz, it was a big job and you were absolutely masterful and head on out now andee you on the air next week.
