I agree with John Yoo and Saikrishna Prakash; @RealDonaldTrump can fire Mueller, but he shouldn't; Trump should exercise prudence and restraint (and so should Mueller).https://twitter.com/nytopinion/status/984733157974069249 …
In light of the thoroughness of the Mueller investigation, I would certainly accept its exoneration of Trump (as to the matters covered by the investigation; DJT faces many other legal issues and controversies, of course).
