CBS News | September 1, 2026 — CBS News contributor Elliot Ackerman discusses the resignation of Army Secretary Dan Driscoll, his reported disagreements with Defense Secretary Pete Hegseth, and what the leadership shakeup could mean for the Pentagon during wartime.

Why Dan Driscoll Resigned

Ackerman examines the internal tensions surrounding Driscoll’s departure, including disputes over senior-level promotions and other personnel decisions. He contrasts those disagreements with Driscoll’s emphasis on modernizing the Army through investments in drone warfare, hypersonic missiles, and other emerging capabilities.

Leadership and Military Readiness

The conversation also addresses the broader turnover among senior Army officers and the removal of officers from promotion lists. Ackerman argues that instability at the top can undermine confidence, continuity, and the stable leadership troops need during a period of active conflict.

What Comes Next

Ackerman also considers the political difficulty of confirming a successor, particularly if control of the Senate changes after the midterm elections.
