The top Pentagon official in charge or personnel and readiness quit Friday after a little over a year on the job, The Hill reported.
Jimmy Stewart was the second top official this week to announce an exit. Defense Secretary Mark Esper accepted Stewart's resignation, but did not give a reason why he was leaving, the news outlet reported.
Stewart was confirmed as the assistant secretary of Defense for manpower and reserve affairs in October 2018 and also filled the under secretary role for personnel and readiness.
In his statement, Esper called the role "critical to the national defense strategy, in support of our families and readiness" and praised Stewart for leaving retirement to take on the job "after having served 37 years in the Air Force," The Hill reported.
The resignation comes a day after the Pentagon confirmed its top Asia policy official, Assistant Secretary of Defense for Indo-Pacific Security Affairs Randall Schriver, will leave the job he has held since January 2018, The Hill reported.
