I think Ben Carson would be a good pick. He can tell Trump how The Swamp operates from the POV of an agency director that has served for some years.
Yep, toss my hat in the ring of Dr. Ben Carson. A man who can NOT be bought.
Vance has proven he is the best of the best......
Not sure about Carson. Heard him on a interview with CNN, he sounded a bit slow to me.
