Does anyone actually think Trump or anyone in his circle colluded with Russia? Of course not, the democrats just made all that up to bog the administration down in endless investigation and controversy. 
Sure there's evidence of Russia hacking the DNC, and NSA intercepts of Flynn and Kushner's communication with Russia prior to Trump assuming office, which Obama promptly leaked to the media to feed a false story. 
But so far, no evidence of collusion or treason. One has to wonder why the NSA hasn't intercepted any more incriminating communications than Flynn discussing the roll back of Obama's sanctions with the Russian Ambassador before Obama left office. 
The real criminals are the people selectively leaking classified information to the media in a way meant to fuel a false naritive.
