At CIA, he did dangerous things, recruited spies, and served 3 times as Chief of Station.

At the Energy Department, he did nuclear weapons. He protected our nuclear secrets while learning about theirs during 2010-2012 as Director of Intelligence and Counterintelligence.

Due to his intelligence expertise, he was promoted to Associate Deputy Secretary of Energy and Acting Undersecretary for Nuclear Security in 2013, where he reversed the decade-long budget decline of America’s nuclear weapons laboratories, helping them get ready for the renewed nuclear threats that we face today from China and Russia.
