Out of 24 Cabinet or cabinet-level positions, 8 are swamp inhabitants. That is pretty good.
Mike Pence (VP)
Jeff Sessions (AG)
Tom Price (HHS)
Elaine Chao (Transportation)
Reince Priebus (Chief of Staff)
Dan Coats (DNI)
Mick Mulvaney (OMB)
Mike Pompeo (CIA)
I did not count Ryan Zinke (Interior) and David Shulkin (VA) because they were not in DC long enough. Yes, it is an arbitrary cutoff.
