Muellers investigation just started. The Senate investigation has only started handing out subpoenas this month. Admittedly, the House investigation is MIA. But the point is, it's still way to early to make the call that there was no collusion between the campaign and elements of the Russia government.
This is from the
APPOINTMENT OF SPECIAL COUNSEL TO INVESTIGATE RUSSIAN INTERFERENCE WITH THE 2016 PRESIDENTIAL ELECTION AND RELATED MATTERS:
Not only can Mueller investigate the Trump campaign's alleged collusion with Russia government, it is the primary reason listed as to why the special counsel was authorized to conduct the investigation.
That's a bit disingenuous. We know quite a bit more than that.
And to that question my answer is, at this point in time, I don't know.
But I think it's the wrong question to be asking. I think the correct question is:
"If the investigations all reach the same conclusion and it is determined that no one involved in the Trump campaign colluded with the Russian government is influence the 2016 election, will I be able to reconcile that with the reckless and incompetent behavior of the Trump White House that all but confirmed an attempted cover-up?"
The answer is still, I don't know.
