I’m guessing Bolton is total bait. Trying to get the D’s to think his testimony is worth exchanging Biden and co if witnesses are called.
Trump did nothing wrong. Ukraine didn’t know the aid was being held in the first place so even if Trump did attach it to Hunter investigation it’s not quid pro quo. Bolton’s testimony won’t contradict that unless he decides to get up there and perjure himself. I don’t think we have anything to worry about.
