 Woo. Andrew Bates, White House spokesman, said on Tuesday the president was working well before the 11 a.m. start time each day after exercising. By exercising, they mean doing pool calisthenics. Still, at a fundraiser on Tuesday evening, Mr. Biden blamed fatigue for his debate performance. He said, I wasn't very smart. I decided to travel around the world a couple times. I don't know how many time zones. He added, I didn't listen to my staff. I came back. I fell asleep on the stage.
