Does SCOTUS have a role here?
I’m not a lawyer but unless DJT can prove that his rights under the US Constitution are being violated my guess is that they don’t.
Nope. Smartest coward in the world, frat boy and miss junior league will not sully the Court with engaging in real controversies under the constitution.
Not yet
However the secret service has a big role to play insuring Trump's safety. There is no way in hell the secret service is going to allow a criminal DA to arrest President Trump. Also the NYPD used to be a honorable entity if the still are they will also not try to arrest Trump. However if Trump is arrested then it falls on the people to set him free.
Where is Trump located right now and why has DeSantis been silent. DeSantis could put Fla national guard at Mar Largo and end this in a NY second.
