President Obama, who campaigned in Miami on Thursday, watched the vice presidential debate aboard Air Force One on the way home to Washington.

Upon landing at Andrews Air Force Base, he told reporters, "I'm going to make a special point of saying that I thought Joe Biden was terrific tonight. I could not be prouder of him. I thought he made a very strong case. I really think that his passion for making sure that the economy grows for the middle class came through. So I'm very proud of him."

Asked if he called Biden afterward, Obama smiled and replied: "Yes, I just talked to him."
