United States Army Secretary Daniel Driscoll has submitted his resignation, according to media reports citing sources familiar with the matter. The reports indicate that Driscoll's departure follows months of significant tension with Defense Secretary Pete Hegseth. The White House has not denied the reports, though it remains unclear if the resignation has been formally accepted.

Driscoll's tenure as Army Secretary has seen the department advance President Trump's agenda, with a spokesperson highlighting his leadership during "historic military operations," a renewed focus on "readiness and lethality," and his involvement in negotiations between Russia and Ukraine.

Spokeswoman Anna Kelly stated that "The United States Army is more powerful than ever thanks to his work alongside the Commander-in-Chief and Secretary of War." These comments were made in response to inquiries about a Wall Street Journal report on Driscoll's resignation.

Driscoll is reportedly considered close to Vice President JD Vance. His resignation marks the latest in a series of departures from senior Pentagon roles under Secretary Hegseth's leadership. This includes the dismissal of Army Chief of Staff Randy George in April and the unexpected stepping down of General Christopher Donahue, the Army's commander in Europe and Africa, in June.

Further departures under Hegseth's watch have included several other generals and admirals, notably the head of the Navy. In April, Navy Secretary John Phelan abruptly left his position, becoming the first head of a military service to depart during President Donald Trump's second term.

The source familiar with the matter told Reuters that the acceptance status of Driscoll's resignation was not clear. The Army declined to provide an official comment on the reports.

These developments occur against a backdrop of significant global military activity, including ongoing US-Israel operations related to Iran, which have impacted regional stability and the global economy. The Pentagon has also recently addressed troop deployment plans for upcoming elections.

The series of high-level changes within the Department of Defense raises questions about the internal dynamics and strategic direction of the US military under the current administration.
