According to Jeff Childers, this takeover is a legal slam dunk for Trump. It’s written into the home rule laws.
Of course corrupt judges make up their own laws.
From what I have seen, the average DC residents are pretty happy so far.
Even worse, it's a federal district per the constitution and per the constitution the Congress writes laws for execution. Unfortunately, under our unitary executive arrangement, Trump has the executive power to ensure that the laws are being properly executed, whatever the arrangement for providing subordinate officers [mayor and DC legislature].
