After graduating from the University of South Florida, he was commissioned into the U.S. Navy in 1986 and went on to serve for nearly three decades. Over that time, he worked in a range of public affairs and communications roles, becoming chief spokesman for the Navy and later serving at the Pentagon.
He became more widely known during his time as spokesperson for the U.S. Department of State from 2015 to 2017. In the Biden administration, he returned to a central communications role, first as Pentagon press secretary and later as White House National Security Communications Advisor.
Known for explaining complex defense and foreign policy issues in clear, direct language, he has remained a prominent figure in public discussions about U.S. national security. After government service, he was announced as the incoming director of the University of Chicago Institute of Politics.
