 This is a special report from ABC News, the Biden interview. I'm Daria Albinger. It's been a little more than a week since the president's shaky debate performance, and tonight he sat down for an exclusive interview with ABC's George Stephanopoulos. You say you were exhausted, and I know you've said that before as well, but you came and you did have a tough month, but you came home from Europe about 11 or 12 days before the debate, spent six days in Camp David. Why wasn't that enough rest time, enough recovery time?
