Personally i dont think Trump did anything impeachable regarding Russia. I think there is a tremendous amount of inuendo and specualtion but thats it.
The left want the world to think Trump made a deal with Putin that would lift sanctions off Russia in return for hacking into the election. Thats absurd and i dont actually think democrats really believe that ever happened. Thats an illusion they are creating.
I do think Flynn may have discussed improving relations and removing sanctions prior ro Trump taking office. Remember, Trump is a deal maker. That doesnt make it right. However, i dont think actual laws were broken.
That said, none of those conversationa involved stealing the election.
In regards to Comey, i think Trump may of said " go easy on Flynn, he is a good guy". He may have said that in a friendly type way. I dont think he went as far as to ask Comey in a serious manner to drop the investigation.
I think Trump was feeling him out and Coney wasnt biting. This display of disloyalty in Trumps eyes is probably the straw that broke the camels back.
