U.S. Army Secretary Dan Driscoll has resigned, according to multiple reports.

Driscoll had clashed with Defense Secretary Pete Hegseth over a variety of issues, including Hegseth's demands that Driscoll remove four officers - two black men and two women - from a promotions list.

"Secretary Driscoll has been highly effective in advancing President Trump's agenda to Make America Strong Again at the Department of the Army by providing outstanding leadership during historic military operations, restoring an emphasis on readiness and lethality, assisting with negotiations between Russia and Ukraine, and more," White House spokeswoman Anna Kelly said in a statement to the Wall Street Journal.

"The United States Army is more powerful than ever thanks to his work alongside the Commander-in-Chief and Secretary of War," she said.

Axios recalled that Driscoll was the youngest army secretary in history and was well-liked within military circles. Although he had clashed with Hegseth, he was friends with Vice President JD Vance.

According to the New York Times, Hegseth had zeroed in on the four officers on the promotions list even though it contained dozens, most of whom were white men.

According to the outlet, Driscoll faced months of pressure to remove the names from the list but refused because of their long records of exemplary service. Finally, in March, Hegseth removed the names himself despite questions over whether he could legally do so. There were still some female and black officers on the promotion list aside from the four who were removed.

Hegseth and Driscoll also clashed over one of Driscoll's senior advisers, Col. David Butler. Fox News reported that Hegseth first pressured Driscoll to remove Butler and then ordered him to do so in February.

"We greatly appreciate COL Dave Butler's lifetime of service in America's Army and to our nation," Driscoll said in a statement to Fox News. "Dave has been an integral part of the Army's transformation efforts and I sincerely wish him tremendous success in his upcoming retirement after 28 years of service."

Driscoll was nicknamed "drone guy" for his work modernizing the army. The website described his rise within the Trump administration as "meteoric." Driscoll had also garnered bipartisan support, with 16 Democrats supporting his nomination to the role during his Senate confirmation.
