Hegseth's Pentagon Overhaul

The story so far

As of September 15, 2026

This is a story about a defense secretary remaking the Pentagon from the top down while the U.S. is at war. It has now become a confrontation with Congress. Rep. Thomas Massie filed eight articles of impeachment against Pete Hegseth, forcing a House vote within two days over alleged illegal conduct in the Iran war and abuses of power. The leadership churn continues alongside this, with the White House confirming Army Secretary Dan Driscoll’s resignation and the Army still without a permanent chief of staff after Hegseth pushed Gen. Randy George into retirement in April.

What began as headline removals has become a fight over the promotion pipeline itself. Hegseth has reached into the slates that feed future leadership, spiking at least six Army officers selected to become two star generals after earlier blocking four one star promotions. On the Navy side, he pulled seven officers off a promotion list, including Rear Adm. Amy Bauernschmidt, the first woman to command a nuclear aircraft carrier, and removed Navy Secretary John Phelan while installing Undersecretary Hung Cao as acting secretary, underscoring that this is not confined to the Army.

The stakes are cumulative: in wartime, continuity and depth of experience depend on who is allowed to move up as much as on who holds the corner offices today. By reshaping promotion lists and removing service leaders, Hegseth is determining who will make operational and budget decisions a year from now as well as next week. The turnover has reached field commands too, with Gen. Chris Donahue set down from U.S. Army Europe and Africa, adding to the strain on steady planning and execution.

Driscoll’s exit explains the direction of travel, clearing a key civilian gatekeeper who could resist interventions in Army priorities and personnel. The impeachment articles place that personnel story beside specific allegations about how Hegseth has run the war, including waging hostilities without congressional approval, killings at sea, retaliation against a sitting senator, and unauthorized operations beyond Iran. The thread that ties the facts together is control, not isolated firings but a consolidation of power over appointments and wartime actions, now set for a recorded vote in the House while the Pentagon’s leadership bench is being rebuilt in real time.
