 J.D. Vance. J.D. sounds cool. That's how he goes. Senator J.D. Vance, now vice presidential nominee. J.D. Vance. The decision coming down yesterday, and apparently it was actually made yesterday. Certainly, judging from J.D. Vance's interview on Fox, he didn't find out about it until yesterday. 20 minutes beforehand is when he found out before the announcement.
