Navy Secretary John Phelan has unexpectedly resigned, marking the first departure of a military service head during President Trump’s second term. The Pentagon did not provide a reason for Phelan’s exit, which comes amid a tense situation involving a blockade of Iranian ports. Phelan, a major Trump donor and outsider with no prior military experience, was appointed in 2024 to bring change to the Navy. His sudden departure follows a series of leadership changes at the Pentagon, including the firing of several top military officials by Defense Secretary Pete Hegseth. Undersecretary Hung Cao, a Navy veteran, will temporarily lead the Navy. Phelan’s resignation is notable as he had recently been active in discussing the Navy’s future plans and budget.
