“You never know what SCOTUS will do”
Who will enforce their decisions?
This whole area is full of danger for a Trump. It is a totally stacked political ploy because half the political segment of the federal government, three quarters of the bureaucracy, and virtually all of the media are hell bent on driving the president from office. They are unwilling to state the obvious and address reality in this whole affair.
Should Mueller obtain a subpoena, and the Supreme Court uphold it, then the court might direct the FBI or Secret Service to enforce the subpoena. Obviously this would violate the separation of powers, but do you really think they’re aren’t members of those two agencies willing to go to the mat to make Trump look bad. You might even have an armed confrontation, maybe even a shootout.
At that point Trump would be impeached and out of office within hours. All for doing absolutely nothing other than getting elected. Then we might reach a Julius Caesar moment when the Senate thinks they’re saving the Republic while they’re actually setting its demise in motion.
