To "get" what Trump was saying, I break "the Russia thing" into distinct and different things.
Mueller's charter is the second point. This is what Sessions is recused from, not because of Russia, but because he was involved in the campaign.
The first point is an issue that everyone agrees is important, but nobody is describing how to deal with it, and what parts of it have to be accepted on 1st amendment grounds. Hacking is a federal crime, and the Russians have a lesser payoff in risking an illegal hack, than players in any political party do.
Back to the original story - the DEMs would have you think that Trump's remark to Holt was referring to the second bullet point. That Trump intends to obstruct investigations into Flynn, Manafort, et al, and if Comey won;t back off after being suggested to, then he's going to fire Comey. That's what the DEMs sincerely believe is the case. Just like Comey takes everything Trump says in the most sinister way possible - they are biased.
