Defense Department spokesperson Sean Parnell acknowledged Phelan’s departure in a brief statement, thanking him for his service without elaborating on the reasons behind the move. Navy Undersecretary Hung Cao has been appointed as acting secretary in the interim.
Reports suggest that Phelan’s exit follows disagreements with senior Pentagon leadership, particularly with Hegseth. Sources indicated that tensions escalated over decision-making authority and communication channels, with Phelan reportedly bypassing established protocols on key defense proposals.
Phelan, a former financier and political donor, had been appointed after Trump’s re-election despite lacking prior military experience. His close ties to the president and direct engagement on strategic matters reportedly caused friction within the department.
The leadership change comes at a critical time, as U.S. naval forces continue operations in the Strait of Hormuz, enforcing a blockade during a fragile ceasefire. The broader conflict, which began earlier this year, has resulted in significant casualties and heightened global economic concerns.
