We have to realize that Mueller is not tipping his hand, so any conclusion vis-a-vis Trump is way too premature. By not doing so, Mueller is playing a wise game, imo, so as to not create at least too much panic with Trump so that the latter doesn’t jump into firing him, which could create quite a constitutional crisis.
But there is indication that Trump believes he’s in trouble, going by his actions, namely firing Comey and also by trying to stop the investigation. If he’s completely innocent, then those actions make no sense.
But we’re just gonna halfta wait and see.
