President Trump moved quickly to install a new acting Army secretary after Dan Driscoll resigned this week, ending months of reported friction with Secretary of War Pete Hegseth over the direction of the nation's largest military branch.
Trump announced Thursday on Truth Social that Adam Telle, currently the assistant secretary of the Army for civil works, would take over as acting secretary of the Army effective immediately. Driscoll had submitted his resignation earlier in the week and said Wednesday would be his "last full day" in the role he held for roughly 18 months.
The move leaves the Army navigating a significant leadership gap. After Driscoll's exit, the service branch has no Senate-confirmed secretary or chief of staff, a situation that has drawn criticism from lawmakers in both parties while the U.S. military remains engaged in active operations abroad.
Driscoll's departure did not come out of nowhere. Fox News reported that the outgoing secretary had clashed with Hegseth "over the Army's transformation and readiness," with Driscoll believing Hegseth had hindered those efforts. The friction reportedly lasted months, though neither man spelled out the disagreements in public.
Behind the scenes, the picture was sharper. The New York Post reported that Hegseth and Pentagon chief of staff Ricky Buria allegedly accused Driscoll, without evidence, of leaking reports about low munitions stockpiles. A Trump administration official told the Post that "Ricky and Pete made it so untenable for [Driscoll] that he felt it was best for not just him but for the people that he loved and respected in the Army to leave."
Driscoll had also raised concerns directly with the White House about Hegseth's firing of Army generals responsible for military transformation and readiness, the Post reported. Those firings removed officers Driscoll viewed as essential to modernizing the force.
The tensions between Pentagon leadership and the Army secretary mirrored a pattern that had been building for months inside the Trump defense establishment.
The AP confirmed that Driscoll spoke directly with President Trump about the state of the Army before submitting his resignation. Among the reported flashpoints was Hegseth's ouster of Gen. Randy George, described as a Driscoll ally in Army leadership.
Driscoll is not the first top military secretary to depart during the ongoing U.S.-Iran conflict. The Washington Examiner reported that Navy Secretary John Phelan left in April, making Driscoll the second service secretary to exit during wartime operations. Driscoll's resignation was submitted effective September 3, though the White House had not yet formally accepted it as of the article's publication.
The Examiner also reported that Hegseth is considering Sean Parnell, the current assistant secretary of defense for public affairs, as a potential permanent replacement for Driscoll.
Earlier this summer, Republican senators openly questioned Hegseth's Pentagon leadership as the Iran conflict stretched past the four-month mark, a sign that the friction was not confined to internal Pentagon hallways.
Sen. Thom Tillis, a North Carolina Republican, did not hold back about the broader implications. He called on the administration to "find a new leader at the Pentagon who will retain and empower our military talent rather than diminish it." Sen. Jack Reed, the Rhode Island Democrat, went further:
"Secretary Hegseth is cultivating a culture where dissent is punished and competence is secondary to personal allegiance."
That bipartisan criticism, a Republican senator and a Democratic senator landing on similar concerns about talent retention, underscores a real problem. When the Army has no confirmed secretary, no confirmed chief of staff, and key nominees stalled in the Senate, the chain of civilian oversight thins at exactly the moment it matters most.
Trump framed the appointment as a seamless transition. In his Truth Social post, the president called Telle "a Great Patriot, who is respected by all." Telle was already Senate-confirmed, having been nominated by Trump and approved for the civil works post in 2025. In that role, he oversees the U.S. Army Corps of Engineers' civil works program, including flood and storm protection, commercial waterways, and Clean Water Act permitting.
Telle's background is heavy on legislative relationships, exactly what the Army may need with nominees stuck in the Senate. He spent a decade in the office of former Sen. Thad Cochran of Mississippi, rising to deputy chief of staff, legislative director, and the senator's top national security staffer. He later served as chief of staff to Sen. Bill Hagerty of Tennessee.
During Trump's first term, Telle led the White House Office of Legislative Affairs' Senate team, serving as the president's chief liaison to the upper chamber. He also worked on the Senate Appropriations Committee subcommittee that oversees the Department of Homeland Security's budget. Those connections could prove useful as the administration tries to push stalled Army nominees through confirmation.
The leak accusations that reportedly poisoned Driscoll's relationship with Hegseth and Buria add another dimension to the personnel churn. If the incoming acting secretary's primary qualification is keeping peace between the Pentagon and Capitol Hill, it suggests the administration recognizes the damage the Driscoll episode has done to that relationship.
Whatever happened behind closed doors, Driscoll's public departure was gracious. In a statement posted on X, the outgoing secretary praised both the president and the man he reportedly clashed with for months:
"I had the privilege of working with them to modernize and accelerate how the Army mans, trains, and equips the most lethal fighting force on the face of the earth. We could not have made the progress we did without the support of Secretary Hegseth."
Driscoll added that he was "forever grateful to President Trump for the opportunity to once again serve my country" and described his tenure as "the honor of a lifetime."
White House spokeswoman Anna Kelly offered a similarly warm assessment. Newsmax reported Kelly's statement that "Secretary Driscoll has been 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."
The gap between those public statements and the reported private reality, leak accusations, fired generals, months of friction, is wide. Driscoll credited Hegseth publicly. Administration officials told reporters the relationship was toxic. Both things sit on the record now.
Driscoll's departure is part of a broader wave of high-profile exits from the Trump administration. Earlier this summer, intelligence chief Tulsi Gabbard left her post in a parting act that drew its own headlines, and the White House recently replaced its White House counsel as well.
The question now is whether Telle can hold the Army's civilian leadership together while the Senate works through stalled nominations, and whether the Pentagon's internal power struggles will let him.
An Army at war deserves a stable chain of command. Right now, it does not have one.
