 Are you ready for J.D. Knight? Welcome to Milwaukee, day three of the Republican National Convention. I'm outside the Fiserv Forum. Inside, J.D. Vance is about to take to the stage for what is known as the convention walkthrough. All of the speakers get a walkthrough. But with J.D. Vance, there's going to be a lot of excitement and anticipation over the U.S. Senator from Ohio and his opportunity to prepare for his remarks tonight.
