President Trump bypassed the Army's second-highest-ranking civilian and installed a Senate-confirmed assistant secretary as acting Army chief, a move that deepens a leadership overhaul already marked by high-profile departures under Secretary of War Pete Hegseth.
Adam Telle, who had been serving as assistant secretary of the Army for civil works since his Senate confirmation in August 2025, took over the top Army civilian post effective immediately on Thursday. Trump announced the appointment on Truth Social, calling Telle "a Great Patriot, who is respected by all." The move came one day after former Army Secretary Dan Driscoll's final day in the role, capping roughly 18 months of service that ended amid reported friction with Hegseth over the direction of the force.
Under federal law governing Army civilian succession, the undersecretary, currently Michael Obadal, would ordinarily step into the top job first. Assistant secretaries, the Army general counsel, and the chief of staff follow in that order. Trump set that sequence aside without public explanation, selecting Telle directly. Obadal has not responded publicly to being passed over.
Driscoll's departure was not a bolt from the blue. The Washington Post, citing people familiar with the relationship, reported that the outgoing secretary repeatedly clashed with Hegseth over the removal of senior Army officers, stalled promotions, and changes to modernization initiatives. Driscoll also raised concerns directly with Trump about what he described as damage Hegseth was doing to the Army, the Post reported.
Trump urged Driscoll to stay through the midterm elections, but Driscoll moved ahead with his resignation. His public farewell struck a markedly different tone from the private tensions. In an X post on September 2, Driscoll wrote that serving as Army secretary under Trump and Hegseth had been "the honor of a lifetime" and credited Hegseth with supporting the Army's modernization push.
Fox News reported that Driscoll's fuller statement went even further, saying the Army "could not have made the progress we did without the support of Secretary Hegseth" and expressing gratitude to Trump for the chance to serve. That language sat uneasily beside the Post's account of months of internal conflict, a gap between the public record and the private reality that neither the Pentagon nor the White House moved to close.
The contrast matters. A departing cabinet official publicly praising the very colleague he privately accused of damaging the service raises an obvious question about how much of the administration's defense messaging reflects genuine alignment and how much is choreography.
Driscoll's resignation added to a growing list of senior departures under Hegseth. Former Navy Secretary John Phelan left earlier this year. Army Chief of Staff Gen. Randy George also departed. Each exit carried its own reported friction with the defense secretary's reform agenda.
Telle's background is legislative, not operational. He spent more than 20 years working for Republican senators, Breitbart noted, including stints with the Senate Appropriations Committee and former Mississippi Sen. Thad Cochran. He later served as chief of staff to Tennessee Sen. Bill Hagerty. During Trump's first term, Telle worked on the White House legislative affairs team, serving as the president's chief liaison to the Senate.
Army spokeswoman Heather J. Hagan confirmed to the Daily Caller News Foundation that the Senate confirmed Telle for his civil works post in August 2025. That confirmation gives him a credential most acting appointees lack: he has already cleared a Senate vote, even if it was for a narrower portfolio overseeing the Army Corps of Engineers' civil works mission rather than the full scope of the secretary's office.
Hegseth endorsed the pick quickly. On September 3 he posted on X:
"Huge congrats to Adam. Strong and whip smart. He is indeed a great Patriot, and will be an immediate asset to the @USArmy."
The speed of Hegseth's praise, posted a day before Trump's formal announcement, suggested the defense secretary was involved in, or at least aware of, the selection well before it went public.
Pentagon spokesman Sean Parnell rejected suggestions that the string of departures signaled dysfunction. As the Associated Press reported, the broader context includes Hegseth's ouster of several Driscoll allies in the Army, including Gen. George. Parnell framed the turbulence differently:
"The premise that the Department is in disarray is completely baseless and an insult to every dedicated professional and warfighter in this building. This is what reform looks like."
Reform or not, the Army's top two civilian positions are now both held by officials who have not been confirmed for those specific jobs. Telle is acting secretary. Obadal remains undersecretary but was passed over for the top slot. The Washington Examiner noted that the arrangement leaves the service's civilian leadership in an uncertain posture, with no permanent nominee announced.
Republican Sen. Thom Tillis of North Carolina offered a blunter assessment, telling reporters that Hegseth "is creating a leadership void at the top of our military ranks." That criticism came from within the president's own party, not from the usual Democratic opposition.
The pattern of internal military tensions with Hegseth now extends well beyond any single personality clash. When a Navy secretary, an Army secretary, and an Army chief of staff all leave under the same defense chief, the question stops being about individual temperaments and starts being about institutional stability.
Trump has not said whom he will nominate as permanent Army secretary. The White House referred questions about the appointment to the president's Truth Social post and offered no additional detail. The Pentagon referred questions to the Army.
Driscoll had once been viewed as a potential replacement for Hegseth himself, according to Washington Post reporting cited by the Daily Caller. That possibility evaporated as the two men's disagreements deepened over officer removals and the pace of reform. Driscoll's departure removed a figure who, whatever his private frustrations, had at least been a counterweight inside the building.
Telle inherits a service branch in the middle of a sweeping leadership overhaul. Senior officers have been pushed out. Promotions have stalled. Modernization plans that Driscoll championed are now in the hands of an acting official whose previous portfolio, Army civil works, dealt primarily with flood control, navigation, and infrastructure projects managed by the Corps of Engineers, not combat readiness or force structure.
Whether Telle's two decades of Capitol Hill relationships give him the standing to manage those fights, or whether he was chosen precisely because he is unlikely to pick them, is a question the administration has not answered. His legislative background may make him an effective liaison between the Pentagon and Congress. It does not, on its own, make him the person to navigate the friction between Army leadership and the defense secretary's office that has already consumed his predecessor.
Reform demands accountability. But accountability runs in both directions, and an Army that keeps losing its top leaders faster than it can replace them is not a reform success story. It is a warning sign.
