text:  From ABC News, I'm Michelle Franzen. President Biden on the campaign trail after last night's debate against Donald Trump and the president raising more concerns about his age after stumbling while answering questions. His campaign says it was due to a cold today at a rally in Raleigh. The president acknowledged he's not young, but says he can tell the truth. I'm here in North Carolina for one reason, because I intend to win this state in November. And you're going to see that happen.
