I watched the second part tonight and am still trying to gather my thoughts. I thought his stating that he was giving public interviews to get the truth out because he doesn't trust the US Justice Dept. under AG Barr interesting, though I'm really not sure what to think about it. A part of me wonders if his view of "Justice" is colored by his growing up under Soviet "justice," or if they really are attempting to make him a scapegoat to protect those more "valuable" to the President.
To be fair, I am taking things Mr. Parnas states with a grain of salt -- though I do tend to trust what he states when he has the documents to back him up. To give one example, that ties into the above, I found it questionable that AG Barr is heavily involved in the Ukraine situation, as Mr. Parnas alleged last night. While I do think AG Barr works frequently as Pres. Trump's "lawyer" (such as whitewashing the "summary" of the Mueller Report), beyond being the AG, at the same time I think he does attempt to curb Trump's worse impulses and stop things Trump might want to do that are illegal/immoral. So I'm skeptical of Barr's being involved with Giuliani's activities in Ukraine.
His talking about Pres. Trump trying to fire Ms. Yovanovitch as ambassador to Ukraine is another one I have issues with. From what I've seen, if Pres. Trump really wanted her fired, he would have Tweeted that she was fired and that would have done it. At the same time, I can't completely discount that he did want her fired, told Sec. Pompeo to fire her, and Pompeo explained that he couldn't do it for whatever reason -- it feels like there may be more story there.
In the end, I think there is plenty there that is quite damning and makes the case that the President abused his power in trying to get Ukraine to announce an investigation into the Bidens. It does leave a lot of questions though, ones that will require Bolton, Pompeo, Giuliani, Perry, and others to testify about if we are going to get to the bottom of things (Perry especially, give the allegations against him when he resigned and Mr. Parnas' allegations tonight).
I did find it interesting that Mr. Parnas stated he believes VP Biden is completely innocent of wrongdoing in Ukraine. I tend to believe him here, both because he seems to have more reason to claim Biden is guilty than innocent as well as how he seems to have evidence, that fits what we know, that both former Prosecutors (AGs) Shokin and Lutsenko were corrupt and were willing to change their stories about the Biden's guilt for the right "price."
I am hoping the Senate will hold a legitimate trial, particularly since they have the Parnas documents, and will attempt to get to the truth of Mr. Parnas' allegations.
