Before Kirkland, he served as a U.S. presidential appointee (with U.S. Senate confirmation) in national security leadership roles, including as Under Secretary of Commerce for Industry and Security, a CFIUS decision-maker, Deputy Assistant Secretary of Defense for Special Operations, and as a member of the Global Markets Board of the National Intelligence Council.
