Quite a few actual attorneys have gotten in rather serious trouble for using A.I. to do their legal research for them.

You're obviously not an attorney, or you would know not to use A.I. to answer legal questions

That's funny. I said I agreed with the AI, which means I read it and recognized it is correct. So let me tell you now, that you don't understand or know the Supremacy Clause and we discussed this same subject Trump's first term. The Supremacy Clause is about conflicts in the laws between the Federal Government and the States.

The Federal Government has full control of immigration in the Constitution, the states have little to say in it, but in practice are influential.

The conflict was that Trump wanted to coopt police in local areas. Take a look at the suit I posted, it was LOCAL POLICE that were being sued for violating 4th Amendment rights. And if you look at the AI Overview you'll see cooperating state agreements, and they also get suits for violating rights like the one I posted.

No, states don't have to enforce immigration laws, but they can make agreements. A state deciding not to cooperate is within its prerogative to do so.
