Army Secretary Dan Driscoll has submitted his resignation, intensifying scrutiny over Defense Secretary Pete Hegseth's extensive leadership changes within the Pentagon. The turnover has sparked debate among lawmakers and analysts about the stability and direction of the U.S. military's top ranks.
Driscoll's exit comes after reports of disagreements with Hegseth regarding the Army's transformation and readiness, with Driscoll reportedly believing Hegseth had hindered these efforts. White House spokeswoman Anna Kelly stated that Driscoll was "highly effective in advancing President Trump’s agenda to Make America Strong Again at the Department of the Army by providing outstanding leadership during historic military operations, restoring an emphasis on readiness and lethality, assisting with negotiations between Russia and Ukraine, and more." She added, "The United States Army is more powerful than ever thanks to his work alongside the Commander-in-Chief and Secretary of War."
However, some in Congress have voiced concerns. Sen. Thom Tillis, R-N.C., has stated that Hegseth is "creating a leadership void at the top of our military ranks." Similarly, Sen. Jack Reed, the ranking Democrat on the Senate Armed Services Committee, has contended that "Hegseth is cultivating a culture where dissent is punished, and competence is secondary to personal allegiance."
President Trump has appointed Adam Telle as acting secretary of the Army, describing him as "a Great Patriot, who is respected by all." Telle previously served as the Assistant Secretary of the Army for Civil Works.
Presidential replacements of senior military leaders are not unprecedented. Historically, presidents have removed commanders when strategic disagreements arose or when a different direction was desired. This practice dates back to Abraham Lincoln, who replaced Gen. George McClellan during the Civil War due to his cautious approach. Harry Truman famously removed Gen. Douglas MacArthur during the Korean War over strategic differences. More recently, President Barack Obama accepted the resignation of Defense Secretary Chuck Hagel in 2014 amid disagreements over policy and strategy.
Under President Trump's second term, reports indicate at least 20 military leaders have departed, attributed to a range of factors including clashes over leadership style, military strategy, and policy disagreements. A senior Pentagon official noted that "changes in civilian leadership at the military-service level aren’t unusual," pointing to Trump's first administration, which saw multiple Army secretaries and acting secretaries.
Conversely, supporters of Hegseth's approach assert that the Pentagon is unified behind his vision. A spokesperson stated, "Secretary Hegseth has been a transformative leader for the Department of War and, at President Trump’s direction, has ushered in a new era of Peace Through Strength. Standards and merit are back, our arsenal is stronger than ever before, and morale and recruitment across every service are at all-time highs." This perspective suggests that Hegseth has "slashed bureaucracy, unleashed innovation, and delivered for our warfighters."
Trump's agenda for his second term has emphasized rebuilding the American military, tightening fitness standards, eliminating diversity, equity, and inclusion policies, overhauling weapons acquisition, boosting recruitment, and refocusing the force on combat readiness and lethality. The administration points to achievements such as the Army hitting recruiting goals early as evidence of renewed patriotism and career opportunities within the service.
