Two and a half years and tens of millions of dollars later, President Trump has been completely and unequivocally exonerated of allegations that he colluded with the Russians in order to influence the 2016 elections. Period.

Attorney General William Barr has made crystal clear that Special Counsel Robert Mueller has determined that while there is ample evidence the Russians attempted to influence the election, there is no evidence at all that anyone in the Trump campaign, or for that matter any American, was involved. Period.

That is something that all Americans should be relieved about and quite frankly proud of. Out of 350 million Americans, not one attempted to assist the Russians in throwing the election.

What will continue to be a sore spot for those who wish Trump was guilty of anything at all is the findings concerning obstruction. Mueller recommended no finding of obstruction, though in his report he listed 10 areas that he felt deserved further consideration by the Department of Justice. The DOJ found nothing sufficient to establish obstruction on the part of the president. In other words, there was no "there-there."

The findings will never satisfy the rabid, radical left who will continue to beat the drum of collusion. It's over, but yet it will never be over as far as some are concerned.

With the Mueller investigation in the rear-view mirror, it is time now to begin searching for answers to the burning questions of just how all this got started in the first place and why. I suspect those questions will yield some mighty interesting answers.

Could be a very interesting summer.
