Army Secretary Dan Driscoll Expected to Leave Post

US Army Secretary Dan Driscoll is expected to step down by the end of 2026, or possibly earlier, according to reports from The Wall Street Journal and The Hill. The reports, citing people familiar with the discussions, say his departure follows months of tension with Defense Secretary Pete Hegseth. A separate report by The Hill said Driscoll is also considering leaving around the end of the year. One source told The Hill that Driscoll had previously indicated that an Army secretary in the Trump administration was expected to serve for about 23 to 24 months.

Driscoll’s spokesperson and Pentagon officials declined to comment on the reports.

Leadership Gaps in the Army

If Driscoll leaves, the Army would be without a Senate-confirmed secretary. The service also currently lacks a Senate-confirmed chief of staff after Hegseth removed Gen. Randy George from the post in April without publicly giving a reason. President Donald Trump has not nominated a replacement for Army chief of staff. Gen. Christopher LaNeve, the Army vice chief of staff and a former senior military aide to Hegseth, is serving as acting Army chief of staff. His confirmation has reportedly faced objections from lawmakers in both parties.

Tensions with Hegseth

Driscoll, a longtime friend and ally of Vice President JD Vance, has been involved in a reported dispute with Hegseth over influence within the Pentagon. According to The Wall Street Journal, tensions emerged early in the Trump administration after Driscoll offered to organize a visit by Trump and Vance with soldiers to discuss Army reforms. The relationship reportedly became more strained after Trump selected Driscoll to negotiate with Ukrainian officials as part of efforts to end the Russia-Ukraine war.

Driscoll had developed a close working relationship with George, and the two pushed the Army’s transformation efforts, including the integration of drones and artificial intelligence into military formations. They also traveled to Ukraine together with Gen. Chris Donahue to discuss peace negotiations with Ukrainian President Volodymyr Zelensky.

Driscoll’s Army Transformation Agenda

A former Army Ranger and venture capitalist, Driscoll has focused on modernizing equipment and improving Army infrastructure. Private companies pledged more than $25 billion for projects including data centers, critical mineral refineries, and dining facilities on Army bases across the US. Driscoll and his family moved out of the house reserved for the Army secretary at Joint Base Myer-Henderson Hall, with his family relocating to North Carolina and Driscoll himself moving into a smaller apartment on base.

At a defense conference last month, Trump praised Driscoll, calling him one of “the best guys” and “a killer.” During a congressional hearing, Driscoll described George as “an amazing, transformative leader.”

Background

Driscoll is a former Army Ranger who served as a Cavalry Scout Platoon Leader with the 10th Mountain Division during Operation Iraqi Freedom. He earned a law degree from Yale Law School and later worked in venture capital and private equity, serving as a senior adviser to Vance. Trump nominated Driscoll as Army secretary, describing him as a former soldier, investor, and political adviser. He was confirmed by the Senate on February 25, 2025, by a 66-28 vote.
