Sen. Thom Tillis (R-NC) became the first Republican lawmaker to call for President Donald Trump to replace Defense Secretary Pete Hegseth.
The retiring North Carolina Republican voted to confirm the former Fox News host to lead the Pentagon, but he said Hegseth's purge of the military's top ranks – including the resignation this week of Army Secretary Dan Driscoll – has created a leadership void during a time of war and showed he's not up to the job.
"I thank @SecArmy Dan Driscoll for his leadership to our Army and service to our country," Tillis posted on X. "Dan was the right man at the right moment to lead our Soldiers and Army, civilians."
Driscoll is among at least 20 generals, admirals and civilian defense leaders who have been fired or pushed out since Hegseth became defense secretary, according to a CBS News review, including the Army, Navy and Air Force's top uniformed officers.
"Our understanding and assumptions of warfare are being challenged in places like Ukraine and Iran, and Dan understands the old way of doing business no longer applies," Tillis added. "He and [former Army Chief of Staff Gen. Randy] George began a transformative period of innovation in how we array our forces and equip our Soldiers. He challenged our legacy approach to manning and procurement. Most of all, he cared deeply about the men and women in our Army formations and quickly earned their respect."
Before his nomination, Hegseth criticized officers he viewed as too focused on diversity initiatives, and as secretary he abruptly dismissed Joint Chiefs Chairman Gen. Charles Q. Brown and Chief of Naval Operations Adm. Lisa Franchetti in February 2025, along with other senior leaders, often without public explanation. A source told CBS News that Black and female officers have been disproportionately removed from promotion lists, and no active-duty four-star women currently serve.
"If we had a @SecWar who maintained the same priorities and forward-thinking, he would be fighting to retain talented leaders like Dan and the many flag officers he has forced into retirement," Tillis wrote. "Instead, he is creating a leadership void at the top of our military ranks."
"I served on Senate Armed Services for 8 years and as chair or ranking member of the Personnel and Readiness subcommittee," Tillis added. "I have never witnessed more inept management of the brave men and women who serve our country. He is intimidated by competence and retreats to ginning up culture wars instead of soberly attending to the vital work of our national defense and the health and well-being of our fighting force. I urge the President to find a new leader at the Pentagon who will retain and empower our military talent rather than diminish it."
