The Morning Brief: Pentagon adrift as Army secretary exits over officer purge

The Army Secretary position sits empty this morning after Dan Driscoll resigned Monday evening following weeks of escalating tension with Defense Secretary Pete Hegseth. Driscoll had warned the White House repeatedly, including Chief of Staff Susie Wiles, that Hegseth's firing or sidelining of more than two dozen senior military officers was depleting the pool of experienced commanders available for future senior posts. The removals included former Army Chief of Staff Gen. Randy George (whom Driscoll had a close relationship with), Chairman of the Joint Chiefs C.Q. Brown (the first Black military service chief), female military service chiefs including Chief of Naval Operations Lisa Franchetti and Coast Guard Commandant Admiral Linda Fagan, regional four-star commanders, and multiple top military lawyers. As of Monday, Driscoll had served as a buffer between Hegseth and the Army leadership; his exit removes that buffer.

Hegseth has stated since taking office in 2025 that he would fire senior officers involved in what he called DEI woke efforts. Before becoming Defense Secretary, he made statements such as "It's completely unacceptable to see fat generals and admirals in the halls of the Pentagon" and "We are leaving wokeness and weakness behind." The Pentagon spokesperson said Hegseth communicates with the president daily and is grateful to serve a commander-in-chief who loves the military. The White House said Trump has complete trust in Hegseth, pointing to results in recent military operations including the war in Iran as evidence of his effectiveness. Foreign Affairs Committee Chairman Brian Mast defended Hegseth's tenure as focused on capability. Senate Armed Services Committee Ranking Member Democrat Jack Reed stated Hegseth was unqualified operationally, experientially, and temperamentally.

Driscoll arrived at the Pentagon as an unconventional choice with no national security experience and a background in venture capital and Republican politics. He served in the Army from 2007 to 2010 as a cavalry officer with the 10th Mountain Division, deployed to Iraq in 2009, and left as a first lieutenant. In 2020 he ran unsuccessfully for North Carolina's 11th Congressional District. He later advised the Trump-Vance transition team and worked for the Republican National Committee. He was widely seen as less combative than Hegseth and became popular on Capitol Hill through work with Democrats including Senator Elizabeth Warren on right-to-repair reforms. Vice President JD Vance, whom Driscoll met at Yale Law School, called him a man of integrity and character. A senior defense official told the desk that Driscoll's departure is a big hit to the Army and that he had served as a buffer pushing back through the White House on Hegseth's officer purge, even if those efforts ultimately did little to slow it.

The Army secretary job has often been marked by turnover in recent decades, with acting officials and tenures of roughly two years or less being common. John McHugh served from 2009 to 2015 under President Barack Obama and became one of the longest-serving in recent decades. Pentagon spokesperson Sean Parnell is widely viewed as a potential replacement and has advocated for the job behind the scenes.
