So Trump is advocating enforcing existing law. So be it.
I think it’s brilliant. The law is already there, all Trump has to do is issue the command to the law enforcement people and they can begin enforcing. And, the Union groups are all in favor of it.
It will APPEAR to be a go-around to Congress (but the law is already there and can be implemented without changing or modifying the law) .. and leave them standing with their mouths hanging open .. “Trumped” again.
