Well, based on trump's habit of deflecting anything he's done and trying to pin it on the side, I guess that conclusively proves he did in fact strong-arm the Ukrainian president.
Also, the whole "who is he? He's betraying me...err, the US" thing is pretty much the entire reason whistle-blowers get anonymity, so I hope we never find out, honestly.
Once again, Trump WH is deliberately stone-walling investigations - trying to keep things secret, trying to bury the complaint, trying to convince people not to speak up or to bear witness. It gets so tiresome. I'm not one to say "if you've done nothing wrong you've got nothing to hide", but man, these guys practically want to keep tomorrow's menu a secret. Of course, with these people, tomorrow's lunch could be unicorn tears and newly born souls, but that's not here nor there.
