text:  News. I'm Tom Rigotti. The first of two debates between President Biden and former President Trump airs tonight at 9 Eastern. Fox Business Network's Grady Trimble has a preview from Atlanta of the CNN presidential debate. This is the first time these two men have been together on the same stage in four years. And there are new rules this time around. No audience and the mics will be cut unless it's that particular candidate's turn to speak.
