And if they don’t like the outcome they should be told thusly: you will be shipped to the foreign totalitarian country of your choice, you and your whole extended family and you will never set foot in the US again; if you’re caught trying to sneak back in or come in illegally, you will be summarily executed.
+100! He is also well within his right to do it now with this impeachment coup.
