Trump names Adam Telle acting secretary of the Army following Dan Driscoll's resignation

President Donald Trump on Thursday announced he was appointing Adam Telle, assistant secretary of the Army for Civil Works, as acting secretary of the Army.

"I am pleased to announce that Adam Telle, the current Assistant Secretary of the Army for Civil Works, will become Acting Secretary of the Army, effective immediately," Trump posted on Truth Social.

"He is a Great Patriot, who is respected by all."

He made the announcement after Army Secretary Dan Driscoll submitted his resignation to the president earlier this week.

Telle, who was nominated by Trump and confirmed by the Senate in 2025, oversees the U.S. Army Corps of Engineers' Civil Works program, where his responsibilities include flood and storm protection, commercial waterways and Clean Water Act permitting.

Previously, Telle served as chief of staff to Sen. Bill Hagerty, R-Tenn., and was Trump's chief liaison to the Senate during the president's first administration, when he led the White House Office of Legislative Affairs' Senate team.

Before that, Telle served on the Senate Appropriations Committee subcommittee responsible for overseeing the Department of Homeland Security's budget. He also spent 10 years in the office of former Sen. Thad Cochran, R-Miss., where he served as deputy chief of staff, legislative director and the senator's top national security staffer.

Telle is viewed as having strong relationships with senators on Capitol Hill, which could prove important as the administration works to confirm Army nominees stalled in the Senate.

The appointment fills a key leadership vacancy atop the nation's largest military branch.

Driscoll's exit came after he reportedly butted heads with Secretary of War Pete Hegseth over the Army's transformation and readiness, including Driscoll's belief that Hegseth had hindered those efforts, Fox News Digital previously reported.

The outgoing Army secretary said Wednesday would be his "last full day" in the position, adding that serving under Trump and Hegseth had been "the honor of a lifetime."

"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," Driscoll said in a statement posted on X.

"We could not have made the progress we did without the support of Secretary Hegseth," he continued. "I am forever grateful to President Trump for the opportunity to once again serve my country."
