Who cares? If there was nothing there, then there is nothing to be frightened about.
No reason for Bolton, Mulvaney and Duffey not to testify, then.
Or the informant, or the whistleblower.
The more the merrier, but I believe you're on the side that doesn't want more witnesses or evidence. Direct witnesses, in particular.
You mean like Shokin, who stated on video that he was in the processing of investigating Hunter for money laundering when Joe ran down there and had him fired? Everybody in the left said his story is FOS because he's not credible.
If they announced the whistleblower must testify, you'll see Schiff Face stomping up and down like a kid in a candy store who didn't get the candy bar he wanted. Nobody believes that this clown had no contact with the whistleblower, and that Schiff doesn't even know who he was.
In spite of impeaching Trump with no just cause, they want to continue their fishing expedition with Trump's help. Why would Trump do that? If they didn't have a solid case, they should have taken it to court to rule that Trump has no presidential ability to withhold records or not allow people to testify.
