Trump has shown a tendency to just ignore procedure and just do whatever he wants. The only reason he wouldn't be able to do that is if he was opposed, but who is going to oppose it? There's a few Democrats, but not even a majority of the electeds. I doubt there's a single Republican that'd oppose. Would the Supreme Court stop him?
I think he can make this as big and stupid as he wants, and unless the masses protest against it he'll get away with it.
