 And I'm Michelle Martin in Washington, D.C. Good morning. President Biden's debate performance last week rattled his supporters and ramped up calls for the 81-year-old to leave the top of the Democratic ticket. First Lady Jill Biden is among those saying the president will not step aside. And at a campaign rally in North Carolina Friday, Biden seemed to be making the case for why, despite the poor showing, he should stay the course. I don't walk as easy as I used to. I don't speak as smoothly as I used to. I don't debate as well as I used to.
