US 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.

Axar.az reports, citing The Associated Press, that 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.

“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 U.S Army.”

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.
