Yes a state AG probably could though I actually meant the U. S. AG. And no, probably no standing to sue the AG. There is something called a Writ of Mandamus which is something ordering a governmental official to perform a purely ministerial function. This is a judgment call so he couldn’t be forced.
Was aware of that but was just trying to enlarge the pool of possible parties to the litigation.
Surely there is one country loving, constitutionally savvy person of standing out there who will champion the cause.
