US President Donald Trump has appointed Adam Telle as acting secretary of the Army following the resignation of Daniel “Dan” Driscoll, whose departure has intensified concerns over leadership stability at the Pentagon amid reported tensions with Defense Secretary Pete Hegseth.

Trump announced Telle’s appointment on Thursday, describing the longtime Republican congressional aide as a “Great Patriot” who is “respected by all.” Telle will assume responsibility for the US Army at a particularly sensitive moment, with American forces heavily deployed in the Middle East amid the ongoing conflict with Iran and the service facing shortages of critical missile-defense systems.

Telle previously served as assistant secretary of the Army for Civil Works, a position he assumed in August 2025 after being nominated by Trump and confirmed by the Senate. His official Army biography says he has responsibility for policy direction and oversight of the Army Corps of Engineers’ Civil Works program.

Unlike his predecessor, Telle is not known for a military background. Instead, he has spent much of his career in Republican politics and congressional affairs. He served as chief of staff to Republican Senator Bill Hagerty of Tennessee from 2021 to 2025 and previously worked for the late Senator Thad Cochran of Mississippi for about a decade.

Telle also served during Trump’s first administration in the White House Office of Legislative Affairs, where he was involved in Senate relations. His experience on Capitol Hill is expected to be particularly valuable as he takes over one of the most senior civilian positions in the US military.

Driscoll Departure Deepens Pentagon Turmoil

Driscoll resigned after approximately 18 months as Army secretary, without publicly providing a detailed explanation for his decision. His departure followed months of reported friction with Hegseth over the direction of the Army, senior personnel decisions and modernization priorities.

According to reports, Driscoll had raised concerns directly with Trump about Hegseth’s intervention in Army promotions and the removal of senior military officers. His departure came after the ouster of Army Chief of Staff Gen. Randy George, one of several senior military figures who have left their positions during Hegseth’s tenure.

Driscoll, an Army veteran who served in Iraq and was considered close to Vice President JD Vance, had maintained relationships with lawmakers from both parties. His supporters in Congress expressed concern that his departure could further destabilize Army leadership.

Senator Thom Tillis, a Republican from North Carolina, criticized the situation, arguing that Hegseth was creating a leadership vacuum at the highest levels of the military.

The latest change means the Army is now facing significant turnover at the top of both its civilian and uniformed leadership structures. Gen. Christopher LaNeve is serving as acting Army chief of staff following George’s departure.

Telle Takes Over at a Critical Moment

Telle’s appointment comes as the Army confronts major operational and logistical challenges. The continuing US conflict with Iran has placed substantial demands on American forces in the Middle East and contributed to pressure on stocks of Patriot and Terminal High Altitude Area Defense, or THAAD, missile interceptors operated by the Army.

The leadership transition also comes as the Pentagon pursues a broader restructuring of the US military under Hegseth. A series of high-profile dismissals and resignations since the beginning of Trump’s second term has raised questions among lawmakers and former defense officials about continuity, institutional expertise and military readiness.

Telle is regarded as having a good working relationship with Hegseth, a factor that could shape the Army’s direction following Driscoll’s departure. The Washington Post reported that Trump bypassed Under Secretary of the Army Michael Obadal, who would traditionally have been expected to take over the position on an acting basis.

Hegseth has praised Telle’s appointment, while Republican Senator Roger Wicker, chairman of the Senate Armed Services Committee, described Telle as a strong partner.

The appointment therefore marks not only a change in personnel but potentially a new phase in the Pentagon’s ongoing effort to reshape the Army’s leadership and strategic priorities. (ILKHA)
