It would be nice if just one prominent Republican could stand up and say “I don’t know if there was collusion with Russia or not. What I do know is that we need to find out, that the American people deserve the truth”. But is power so important that they’d rather have it than protect our country, our democratic values?
Personally, I can’t say whether or not there was collusion with Russia or not. Mueller might know, but I don’t have access to the things he’s discovered so I can’t say. What I can say is that if someone, a citizen or resident of the United States, worked with Russia, or any foreign power for that matter, to undermine and distort the political and electoral processes within the United States, well, there’s a word for that: Treason
