The POTUS absolutely has the right. The constitutional right!
Evidently not. Not! Hahahahaha.
Hold on to your panties, this isn't the only thing that Trump does that will fail and fail miserably. His impetuosity and impulsive behavior is going to boomerang his ass again and again.
He let some minor league idiot, Steve Miller, draft the ban. He probably never even read the damn thing before he signed it. He's a total asshole.
Got it yet? I was right from the beginning: Trump will fuck this country up with his bullshit and stop its progress in the name of his Drama Queen-in-Chief antics.
