Sorry about overquoting in the prior posting. I'm making a long overdue update to the Subject header for this afterthought: [...]
2. The Toddler could unilaterally rescind the Executive Branch regulations that assign supervision of Special Counsels to Rosenstein as acting head of the Justice Department (given Sessions's recusal) -- and then fire Mueller personally.
Either of these two tactics would then of course be subject to immediate court challenge. As with the firing of Cox, judges might well find that the actions had illicit purpose. Meanwhile, Congress and the American people would also explode, and we would have endless fun.
Even _if_ The Toddler starts either coercing and firing people or rescinding Executive Branch regulations and firing people, it's probably already too late. One of Mueller's known tactics is sealed indictments. It's rather likely that, if The Toddler starts trying to give Mueller the Archibald Cox treatment, Mueller will make a quick telephone call and order unsealing of a few dozen Federal indictments already issued by a Grand Jury against top Trump Administration officials, quite possibly including Trump and sundry culpable members of his family. Ah, you might think, but cannot Trump as the head of the Executive Branch quash those or just use the broad power of Presidential pardons? No, he cannot quash Grand Jury indictments, _and_ it's widely speculated that judges would disallow any Presidential pardons carried out for entirely illicit purposes. And _moreover_, it is widely suspected that Mueller has been closely coordinating aspects of his investigation with _state_ prosecutors, notably those in Trump's native New York State. A President's power of pardoning extends only to Federal legal matters, and he/she has no auhority over state prosecutions. Thus, it's widely held that if The Toddler attempts any of the apocalyptic measures I've mentioned, attempting to through the Republic into a sort of constitutional crisis such as pertained in October 1973, he actually would achieve only an epic own goal, and in short is fscked already. (The GOP currenly dominant in the House and Senate might also at that point reach their limit and remove him.)
