 NBC News Radio. I'm Lisa Carton. President Biden is self-isolating with COVID in Delaware as pressure mounts on him to drop his reelection bid. Jan O'Malley Dillon pushed back against reports that the president was considering exiting the race. I'm not here to say that this hasn't been a tough several weeks for the campaign. There's no doubt that it has been. And we've definitely seen some slippage in support, but it has been a small movement.
