Overview

  • John Ullyot, former acting assistant to the Secretary of Defense for public affairs, will leave his position at the Pentagon by the end of this week after being asked to resign.
  • Ullyot's departure comes after he and Secretary Pete Hegseth failed to agree on a new role for him within the Department of Defense.
  • Three senior Pentagon officials—Colin Carroll, Darin Selnick, and Dan Caldwell—were recently placed on administrative leave as part of an ongoing leak investigation.
  • Ullyot oversaw a controversial directive to remove diversity, equity, and inclusion (DEI) content from military websites, including a temporary removal of a page honoring Jackie Robinson, which sparked public backlash.
  • Sean Parnell, a former Army ranger and congressional candidate, replaced Ullyot as Pentagon spokesperson in February, marking the start of rapid leadership changes in the department.
