Live Updates: Georgia Senate runoff elections

Democratic Sen. Raphael Warnock is defending his Senate seat against Republican challenger Herschel Walker in a runoff election in Georgia Tuesday, after days of record-breaking early voting in the state. 

On Tuesday morning, CBS News' Nikole Killion asked Walker what he thought the outcome of the race would be. "We're going to win by 100,000," he predicted at his sole campaign stop today at the Marietta Diner.

Warnock, meanwhile, spoke to canvassers and reporters on Tuesday, saying he felt good and he told Killion that he had no regrets about the way he campaigned. "I hope that people will continue to show up – I've seen people stand in the rain for a concert and there's really too much at stake," Warnock said.
