It might be fun to see Hunter questioned, but what could he actually know about the two charges of the Impeachment. Bolton is the one to worry people.
It’s not what he knows, but his “job” and how he got it and his lack of qualifications points to the former VP getting a kickback for the money Ukraine got from us. Trump not only is justified in asking, but has a duty to make Sure our money isn’t wasted. As in one million a year for a job he doesn’t even go to.
