We couldn't prove any form of conspiracy largely due to the fact that the participants didn't think they were doing anything wrong, which is the kind of crazy laws that apply to the powerful that don't apply to the governed (I certainly can't use that kind of logic if the cops show up at my door about something or I get pulled over while driving).

And collusion with a foreign nation doesn't exist as a specific crime, but in a more sane time it would have been easy to see it was what was intended by "high crimes and misdemeanors".

Russia and the Trump campaign worked together to win an election. That doesn’t alarm you? You sound like liberals do when I bring up the Clintons making millions of dollars for speeches at Goldman Sachs and Citigroup after them and Rubin gutted Glass-Steagall and other regulations that benefited investment banks.

Try to look at it objectively.
