Deputy chief of staff to the US secretary of defense has resigned three days after US President Donald Trump fired her boss Mark Esper.

Iran Press/America: A US defense official told CNN Thursday that Alexis Ross has handed in her resignation, making her the third member of the Defense Department to exit the team in as many days and the latest in a growing number of agency officials to leave the Pentagon this week amid a rapidly escalating post-election overhaul.

Ross joined the Defense Department under now-fired Defense Secretary Esper in late-2019 after having served as the Deputy Assistant Secretary of the US Army for Strategy and Acquisition Reform, Daily Mail reported.

Chief of Staff to the Secretary of Defense Jen Stewart had already submitted her resignation Tuesday, one day after Esper was fired. 

The shake-up among Esper's undersecretaries at the Defense Department comes as little shock after sources told CNN Tuesday Trump planned to get rid of the rest of the ousted Defense Secretary's team after firing him. 

Concerns are growing among officials about what lies in store next as the president's overhaul of top brass could be setting the nation up for a chaotic transition to the Joe Biden administration.
