Republican senator calls on Trump to fire Secretary of Defence Hegseth

United States Senator Thom Tillis has called on President Donald Trump to fire Secretary of Defence Pete Hegseth for creating a “leadership void” within the military amid the ongoing war with Iran.

In a social media post on Wednesday, Tillis contrasted Hegseth unfavourably with former Army Secretary Dan Driscoll , who submitted his resignation on Monday amid reported disagreements with the Pentagon chief.

“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,” the North Carolina senator wrote.

“I urge the President to find a new leader at the Pentagon who will retain and empower our military talent rather than diminish it.”

Tillis is a member of Trump’s Republican Party. But in recent years, he has become an increasingly vocal critic from within the party over policies he fears harm democracy.

In June 2025, amid criticism from Trump, Tillis announced he would not be seeking re-election in November’s congressional midterm polls. His term ends in January.

Early in Trump’s second term as president, Tillis was among the senators who voted to confirm Hegseth, a military veteran and former TV host, despite criticisms of his conduct towards women and his past work.

Tillis only confirmed his vote in favour of Hegseth at the last minute, appearing to share some of the concerns being debated in the Senate.
