Chief Pentagon spokesperson Dana White announced on Twitter Monday that she will be leaving the Department of Defense. “I appreciate the opportunity afforded to me by this administration to serve alongside Secretary Mattis, our Service members and all the civilians who support them,” White wrote on Twitter. “It has been my honor and privilege. Stay safe and God bless.” White’s departure comes only days after Secretary of Defense James Mattis resigned with a scathing letter to Trump. The circumstances of White’s departure remain unclear. Charles E. Summers, Jr., who served as the principal deputy assistant to the secretary of defense in White’s office, will take her place as the acting assistant to the secretary of defense for public affairs on January 1, 2019.
