GREGG JARRETT: He never spoke to Trump about this subject. So like so many other witnesses he's offering nothing more than speculation based on rank hearsay but the media, of course, is in a lather. "Oh Parnas! This breaks the case wide open, we've gotta call him as a witness." Trust me on this Parnas will never be called as a witness in the impeachment trial that would ruin any credibility associated with it. And after all, look at what Parnas is saying he's saying “Oh Donald Trump tried to pressure Ukraine into investigating Joe Biden and his son,” that's already evident from the transcript of the telephone call between President Trump and Zelensky and also admitted by Trump himself, that he asked Ukraine “Please look into Joe Biden hand over any evidence of potential corrupt acts by Joe Biden.” So there's not much there, there, plus the fact that this guy's got no credibility whatsoever. He's not gonna be a witness.
