Not at all.
Even if Vindman despised the President, he can't speak disparagingly about Trump as long as he's on active duty. Doing so is a violation of Article 88: Contempt Towards Officials.
The Commander In Chief ordered Vindman to not cooperate with the impeachment process. If Trump gave that order to keep Vindman from disclosing classified information, then Vindman has violated Article 92, Failure To Obey An Order Or Regulation.
Either way, Vindman's career is over...
The problem with lies is the truth..
I watched a lot of his testimony, and he bent over backwards trying to be impartial.
You need more than lies. Not that you have anything more, just that it's needed if you don't want to obliterate your credibility.
