 News. I'm Therese Crowley. President Biden won't budge. Sending House Democrats a two-page letter saying the voters have spoken. Refusing to step aside as the presidential nominee. With his surprise appearance on MSNBC Morning Joe about his bad debate and mental fitness. Let me put it this way. If there was something that was wrong that night, it's not like it comes and that's one night and goes away. That's why I've been out. I've been testing myself.
