Here is a first-hand witness that conservatives have been pining for. Here is a summary of what he said.
1. There was a quid pro quo.
2. Military aid was withheld.
3. A state visit was offered in exchange for an announcement of an investigation.
4. Trump directed the operation from the White House.
5. Rudy directed the ground operation.
6. Trump didn't care about corruption at all. He didn't even want a real investigation. He simply wanted an announcement of an investigation so he could use it for political purposes.
7. All of the aforementioned people were in the loop and participated in the scheme or had full knowledge that it was going on.
The only question is are Republicans in the Senate going to endorse Trump's crimes? Most of them are telling reporters today that they have been too busy to watch the hearings and don't know whats going on in them.
