BILL HEMMER (CO-ANCHOR): Generally speaking then, and based on that answer, do you think they use witnesses in this trial or not? What is the agreed-upon decision, do you think? 

TREY GOWDY (FOX NEWS CONTRIBUTOR): I think they don't. Because you can't just say, “We want John Bolton, but we don't want this witness, and we want Mick Mulvaney, but we don't want this witness.” Either call them all, or make the House do what they should have done, which is talk to all of these witnesses themselves. They’re the ones with the charging power. They’re the ones who made the decision not to call Mike Pompeo, or Mick Mulvaney, or John Bolton, or Rudy Giuliani. So either call all the witnesses, or don't call any of the witnesses, and make the House prove its case based on what it has.
