WASHINGTON — President Donald Trump on Thursday named Adam Telle, a civilian leader in the U.S. Army Corps of Engineers, as the acting Army secretary following the departure of Dan Driscoll amid widespread reports of tensions with Defense Secretary Pete Hegseth.
Telle is currently the assistant secretary of the Army for civil works. But he spent more than 20 years working for Republican senators as well as in the White House during Trump’s first term, serving as the president’s chief liaison to the Senate, according to an Army bio.
“He is a Great Patriot, who is respected by all,” Trump wrote in a Truth Social post.
Hegseth echoed that in his own post on X.
“Huge congrats to Adam. Strong and whip smart,” Hegseth wrote. “He is indeed a great Patriot — and will be an immediate asset to the @USArmy.”
Driscoll gave no explanation for his decision to quit this week as the Army’s top civilian official. His clashes with Hegseth have been widely reported, and some of Driscoll’s allies in the Army were ousted this year by Trump’s Pentagon chief.
Telle has been at the Army Office of Civil Works since August 2025, according to Legistorm, a website that tracks lawmakers and Capitol Hill staffers. Before that, Telle worked as chief of staff for Republican Sen. Bill Hagerty of Tennessee from 2021 to 2025.
Telle spent 18 months working in the White House during Trump’s first term and 10 years working for the late Republican Sen. Thad Cochran of Mississippi, according to Legistorm.
Telle also worked as the chief staff member on the Senate Appropriations Committee’s Homeland Security Subcommittee, according to Hagerty’s remarks when Telle was nominated for the civil works job in May 2025.
In his most recent job, Telle focused on matters involving commercial navigation, flood damage reduction and permitting under the Clean Water Act.
Telle issued a statement in August about the approval of a company’s plans to reroute an aging oil pipeline around a Wisconsin tribal reservation. In May, he was quoted in a story in The Forum, a newspaper in Fargo, North Dakota, about a $3.2 billion flood control project that will protect more than 200,000 people.
Telle will now be overseeing the nation’s largest fighting force at a time when the U.S. is still engaged in conflict with Iran and significant Army forces are stationed in the Middle East.
The war has significantly contributed to the U.S. military’s shortfall in critical weapons like the Patriot and THAAD defense missile interceptors systems, which are operated by the Army.
Driscoll, an Army veteran who served in Iraq, is a friend of Vice President JD Vance and had good relationships with both Republicans and Democrats in Congress.
His allies in the Army who were ousted by Hegseth included its top uniformed leader, Gen. Randy George. Gen. Christopher LaNeve took over as the Army’s acting chief of staff and recently pulled the plug on a drone modernization program that Driscoll had championed.
Driscoll spoke with Trump on the current state of the Army before he submitted his resignation, The Associated Press has reported.
Driscoll did not allude to any problems in the only public statement on his departure, saying Tuesday that it has been “the honor of a lifetime” to serve as Army secretary under Trump and Hegseth.
Democrats and Republicans lamented Driscoll’s departure, with some blaming Hegseth directly.
Sen. Thom Tillis, a North Carolina Republican who is retiring and sometimes has clashed with Trump, said on social media that Hegseth “is creating a leadership void at the top of our military ranks.”
