Mueller Probe Over, but...

This question remains unanswered. I have yet to hear a plausible explanation...

One question:
What the Mueller probe established, according to the AG, is that the Russians hacked the DNC and engaged in an aggressive, covert campaign to influence our election.
So why did @realDonaldTrump stand next to Putin in Helsinki and meekly accept his denials?
