Excellent read on four specific ways Trump is ‘trying to be (a ) king’ -here are brief summations
CNN: 4 ways Trump is trying to be king
Precedent 1: Delegitimating oversight
If Trump's posture is legitimated by Congress and the courts through their own inaction, this decision would constitute a major step in significantly eroding the ability of the capacity of the legislative branch to hold the president accountable.
Precedent 2: Using the bully pulpit for disinformation
The reckless abandon with which he uses his presidential platform to pollute the public discourse with falsehoods is a brazen and aggressive use of authority.
Precedent 3: Legitimating conflict of interest
The President's ownings are directly related to major policy decisions that he makes on a regular basis, including foreign policy.
The President's insistence that the business did not have to be broken up or placed far away from his immediate family was a raw assertion of power.
Precedent 4: Using national emergency power to replace legislating
If the courts don't strike it down, this will offer a model for future Democratic and Republican presidents to obtain monies that they want without congressional approval…Unless Congress figures out a way to push back, the presidency will be much more imperial when Trump is done with his time in office, leaving future Congresses to confront a White House that will be able to inflict much greater damage on other institutions without any sense of restraint.
