Chris Christie has too much baggage and is hardly someone who thinks like President Trump. He screwed-up the transition period beyond comprehension. He IS politically connected but to all the wrong people.
Find him a retired Navy chief or gunnery sergeant. They know how to lead men and know who is the boss: the guy who got elected. They can delicately, predictably tell that congressman or bureaucrat that they are SOL seeing the president that day because the boss says so.
