There is no process. States cannot just up and say “see ya” on their own, we fought a war over that.
If the people felt that it would be OK for a state to leave, the proper thing to do would be to pass an amendment stating a process, and then the state would do it. There would be a lot of details to hammer out: does the State get to keep Federal property (like military bases)? Does it inherit a share of the deficit? What happens to deferred US taxes on things like 401k accounts?
IMHO it would take so long to hammer that stuff out that it’s basically impossible.
Congress won’t rein him in because they know Trump has an army of brown shirts who attacked Congress once already, and who owes Trump their freedom. Those J6 chuckleheads can openly attack Republicans with insufficient loyalty, and Trump will probably just pardon them again.
