Who was the guy he brought onstage and said something like. That’s a good idea and I’ll put you in charge of it? Something about the VA? I can’t remember.
“ Trump (and the country) would be better served by picking his cabinet from one of his rally crowds”
Most people like that would be completely overwhelmed by the permanent bureaucracy and would be unable to function. Unless you are talking about “cabinet” like Secretary of Transportation. The Secretaries of State, Defense, Treasury and the Attorney General are not going to be picked out of crowds at a Trump rally.
Perhaps a rally member or two could be advisors at large. No specific responsibilities, but serve as a sanity check.
