Well, yes and no. Maybe there is information out there that I missed. My understanding is that there is no significant question as to what was said in the call, but the question is what was in the minds of the parties to the call -- the two presidents. Whether Trump was making aid contingent on investigation of the Bidens and/or whether the Ukraine president thought that was the case.
Of course, even if that was the situation, there's a question of whether it's an impeachable act, but that's not what I was addressing.
My understanding is that both men deny there was a quid pro quo. Is that not the case?
Getting back to my original post, I think the reason the Republicans are chasing the whistleblower is that they are trying to build a case that he/she was part of a coordinated effort with Schiff. In other words, that he/she isn't really a whistleblower in the sense that is usually defined.
