I wonder if they actually have any evidence or are just arranging a political lynching. Seems to me that they've had a devil of a time trying to find any dirt.
Having corrupt aides is bad. But there will continue to be people who demand dirt on the actual person in question before considering impeachment.
Would you like to point to any of those people and link the crimes to Trump some how? What you did is just give a laundry list of cases that could be torn apart individually. Nothing is related back to the core issue of conspiracy/collusion or even obstruction.
