Have to laugh...
A huge Republican defense of Trump pushing for the Ukraine investigation is that it was motivated by a heartfelt concern for corruption. It was fully justified therefore not political, the argument goes.
So...Russia hacks our Democratic process in order to elect Trump. Trump campaign officials have numerous (literally hundreds) of ties to Russians, including a meeting in fucking Trump Tower. The Trump campaign publicly lies about what they know about those efforts. They also lie about financial dealings they have going on in Moscow. The head of Trump's campaign is sharing polling data with a Putin intermediary. A top and trusted Trump advisor is coordinating with a known Russian hacking front. Trump tells Flynn to commission a guy who they thought had Russian contacts to find the so called deleted emails, and he does it...it goes on...
You could argue that none of this is evidence of collusion if you like. You'd be wrong, but sure, live in your aluminum foil helmet.
But to argue that none of this justifies an investigation, and that looking into any of this must be a politically motivated hoax?
That's whackadoodle, man. Republicans are pathetic.
