Despite Esper’s efforts, the departures keep piling up. Six senior officials have tendered their resignations in the past month, including four who require Senate confirmation to replace: Navy Secretary Richard Spencer, Assistant Secretary of Defense for Indo-Pacific Affairs Randy Schriver, Assistant Secretary of Defense for Manpower and Reserve Affairs James Stewart, and Principal Deputy Undersecretary of Defense for Intelligence Kari Bingen. Steven Walker, the director of the Defense Advanced Research Projects Agency, and Tina Kaidanow, the senior advisor for international cooperation in the Office of the Under Secretary of Defense for Acquisition and Sustainment, are also stepping down.
Of 59 Senate-confirmed positions, 15 are currently vacant, according to a department spokesperson–and that number will rise to 18 when Schriver, Stewart and Bingen depart. Adding to the strain on the senior leadership, multiple officials, including Stewart, are serving in two senior roles at once.

Chief management officer
