Jimmy Stewart, the acting undersecretary for personnel and readiness at the Department of Defense, has left his post on Friday, Military Times reported Saturday. Matthew Donovan, undersecretary at the U.S. Air Force, will succeed Stewart in the acting administrator role.
Prior to his previous role, Stewart worked as an assistant secretary for manpower and reserve affairs at DoD. He also served under the Air Force for 37 years and has logged more than 4,700 mission hours as a command pilot.
“Jimmy, who was confirmed as the assistant secretary of defense for manpower and reserve affairs in October 2018, has been filling the undersecretary role since then, a role that is critical to the National Defense Strategy, in support of our families and readiness,” said Mark Esper, DoD secretary and 2019 Wash100 Award recipient.
Shon Manasco, assistant secretary for manpower and reserve affairs at USAF, will replace Donovan on a temporary basis.
