He’s a hard worker, and extremely dedicated to his job, loyal to the president, but he didn’t consider his work to be partisan—a careerist Secret Service agent who had served under several Democrat and Republican presidents. He was always respectful, and would run most decisions by Mark or, in his absence, me. But he also wasn’t afraid to tell us hard truths. I left his office that night certain we would work well together, and pretty sure we’d become close friends.
