Time to play for real, boys. Don't give them time to destroy evidence or meet with other members of the 'Deep State' to get their stories straight. Haul his damned butt in there, put him under oath and see what he has to say.

When Donald is producing silks and frogs with his right hand and smoke issues from his nose try to focus your attention on his left hand which has the fog around it as it deftly and without undue attention turns knobs and pushes buttons.
