The goal should be messaging to everybody else. Especially those who might like the outcomes of Trump's crimes but would prefer not to have a president that just smashes through the law to get there. A way to help achieve this is to repeat, over and over and over, that Trump's actions are violating shitloads of laws.
Companies can declare bankruptcy and fold their hand: governments, notsomuch.
Jack Welch is the reason corporate America is a shit show, and GE is a joke.
So...Trump is breaking the law and getting away with it. What else is new?
Yes
He has immunity
BUT... even if the executive is under legal theory constitutionally unitary, it isn’t actually unitary, it consists of individual people who act based on their own perception of legitimacy, and when the President abandons the principle of government of law and not arbitrary individual will in dealing with the courts, well, that also threatens the theoretical infrastructure that binds the people carrying guns in various executive departments to his authority, and we can very quickly end up in one of those highly unpredictable periods of history that produces lots of really neat stories to read about afterwards but is somewhat less pleasant to live through.
