Army Secretary Dan Driscoll resigns amid tensions with Hegseth: Sources

Army Secretary Dan Driscoll has resigned from his position due to escalating tensions with Defense Secretary Pete Hegseth, according to a U.S. official who spoke to ABC News. The White House acknowledged Driscoll's contributions and praised his effectiveness in advancing President Trump's agenda while serving at the Army Department.

He played a crucial role in enhancing military readiness and lethality, facilitating negotiations between Russia and Ukraine, and other significant achievements. However, Driscoll and Hegseth had disagreements on several issues since assuming their roles in 2025. Notably, Hegseth removed or sidelined several senior officers for promotion to general, including former Army Chief of Staff Gen. Randy George, without providing a clear explanation.

Driscoll maintained a close working relationship with George and testified before a congressional hearing that he was unaware of the reasons behind George's removal. Driscoll's selection to lead the diplomatic mission aimed at restarting Ukraine-Russia peace talks, despite his primary responsibility being oversight of military training and equipping, demonstrated the trust placed in him by President Trump.

He was also well-regarded on Capitol Hill and enjoyed the White House's proximity, largely due to his previous connection with Vice President JD Vance, whom he met at Yale Law School during his service in the 10th Mountain Division.
