If this is a question about illegals in general, there’s a lot of problems that need fixing. How many states allow illegals to get driver’s licenses, food stamps, in-state college tuition, and so on?
We need to turn that stuff off. I’m all for a wall too, but the other thing that needs to happen is simply making our country less hospitable to illegals. It’s like a flame and a moth; turn the damn light off, the moths stop coming.
All those actions except maybe tuition are agains current Federal Law, they could start by directing the Attorney General to enforce those laws.
