Big time corporate lawyer. Connected to Time-Warner, and also connected to Kirk & Ellis lobbying firm, where Pres. Trump seems to get most of his high-profile nominees.

"Youse guys want more jerbs? You need a second term, bigly. Send me one of those Bush guys who don't take kindly to those non-Kirk & Ellis Bush guys."
