President Donald Trump appointed Adam Telle as acting secretary of the army on Thursday, filling the vacancy left by Daniel Driscoll. Telle, who currently serves as the assistant secretary of the army for installations, will take charge of the country's largest combat force at a time when the military faces serious challenges on the battlefield and in its internal organisation.
The departure of Daniel Driscoll occurred despite widespread reports of deep tensions between him and Defence Secretary Pete Hegseth. Driscoll, a military veteran who served in Iraq, remained in the post of the military's highest civilian official for 18 months. Although he did not provide a detailed explanation in his public statement, he stated that it was an 'honour of a lifetime' to serve under Trump and Hegseth, and that progress was not possible without the support of the secretary of defence.
Despite the formal tone of Driscoll's statement, the political background of his departure indicates serious conflicts within the upper echelons of the Pentagon. Some of Driscoll's allies in the military, including his top uniformed leader, General Randy George, were dismissed by Hegseth this year. General Christopher LaNeve has taken over the role of acting chief of staff, and has recently halted a drone modernisation programme that Driscoll had championed. Some directly accuse Hegseth of Driscoll's departure, while Senator Thom Tillis warns of a leadership vacuum in the military ranks.
Adam Telle has extensive experience in the legislative process, having spent 20 years working primarily for legislators in Congress. He was head of the office of Republican Senator Bill Hagerty from 2021 to 2025, and previously worked for more than ten years for the late Senator Thad Cochran. During Trump's first term, Tasse spent 18 months in the White House as the president's special assistant for legislative affairs. Trump rated Telle as 'a great patriot' whom everyone respects on the social media platform Truth Social.
The new administration takes control of the military in an extremely tense security context. The US is still involved in a conflict with Iran, with significant military forces deployed to the Middle East. The conflict has significantly contributed to a shortage of critical weapons in the US military, particularly in the Patriot missile interceptor system and the Terminal High Altitude Area Defense (THAAD) system, which are operated by the army. Driscoll spoke with Trump about the current state of the military, which was confirmed by the Associated Press, but in his short statement he did not mention these issues.
The reaction to Driscoll's departure was mixed. Although both Democrats and Republicans expressed regret at his leaving office, pressure on Hegseth is growing. Driscoll had good relations with Republicans and Democrats in Congress during his term, and was also friends with Vice-President JD Vance. His departure leaves a gap in the leadership of the military at a time when stability is needed due to the escalation of the conflict in the Middle East and a critical shortage of defensive resources.
