Tillis calls Hegseth confirmation vote his 'biggest regret' in new book

His biggest regret of a career in public service
Tillis's characterization of his vote to confirm Hegseth as Defense Secretary, revealed in a forthcoming book.

So Tillis is saying his vote for Hegseth was his biggest regret. That's a pretty stark thing to put in a book. What changed his mind?

Mimi

The source material doesn't specify exactly what shifted his thinking—whether it's how Hegseth has performed in the job, or whether Tillis simply had doubts he didn't voice at the time and is now being candid about them.

Luke

Right, and that's important. We know Tillis says it's his biggest regret. We don't actually know why. We know Hegseth's confirmation was controversial, but the source doesn't detail what specific concerns Tillis had or has.

Mimi

True. The confirmation itself was contentious—there were questions about his background and qualifications—but the reporting here is really just about Tillis's statement in the book, not a deep dive into what those concerns were.

Mark

Does this change anything about Hegseth's position? Can a senator's regret actually matter at this point?

Luke

No, it doesn't change his position. Hegseth is still Defense Secretary. This is Tillis processing his own vote, not a move to remove him or anything like that.

Mimi

It does matter symbolically though. A Republican senator saying his confirmation vote was his career's biggest mistake is a pretty significant statement about how that appointment is viewed in hindsight.

Mark

Do we know if other Republicans feel the same way?

Luke

The source doesn't say. This is just Tillis. We don't have reporting on whether other senators who voted for Hegseth share his regret.

Mimi

Which means the story is really about Tillis's personal reckoning, not a broader Republican reassessment—at least not yet.

Mark

And the book is forthcoming, so this is a preview of what's in it?

Luke

Yes. The AP is reporting on what Tillis says in his book before it's published. We don't have the full context of what else he says about the vote or about Hegseth.

  • A sitting Republican senator has publicly broken from party solidarity to declare his own confirmation vote a career-defining error — a rare and disruptive act of political self-indictment.
  • Hegseth's confirmation was already shadowed by doubts about his qualifications and conduct, and Tillis's confession reignites those concerns with the authority of an insider's remorse.
  • The book format signals this is no offhand remark — it is a deliberate, considered reckoning, suggesting the weight of the vote has compounded rather than faded over time.
  • Tillis's candor may fracture Republican unity on executive appointments, quietly pressuring colleagues who cast similar votes to confront their own assessments.
  • Hegseth remains in office, unchanged by the senator's regret — yet the confirmation battle now lives on as an open wound in the political memory of those who shaped its outcome.

In the quiet of retrospect, Senator Thom Tillis of North Carolina has done something rare in the theater of American politics: he has named his own mistake. In a forthcoming book, the Republican senator identifies his vote to confirm Pete Hegseth as Secretary of Defense as the single greatest regret of his public career — a confession that speaks not only to one man's conscience, but to the enduring weight of consequential choices made under political pressure. The admission arrives years after the confirmation, when the deed is done and the office is held, leaving reflection as the only available remedy.

Senator Thom Tillis of North Carolina has written in a forthcoming book that his vote to confirm Pete Hegseth as Secretary of Defense is the greatest regret of his career in public service. The admission is striking in its directness — a deliberate act of self-examination from a senator who had the power to vote either way and chose to support a nominee now viewed, at least by Tillis himself, as a serious error in judgment.

Hegseth's confirmation had never been without controversy. Questions about his military background, his policy positions, and his readiness for the role had circulated widely, even within Republican circles. Tillis voted yes nonetheless — and has since come to view that choice with considerable remorse.

What makes the revelation notable is its format and its rarity. Senators rarely revisit their votes with public regret; the culture of the chamber tends toward forward motion and institutional self-defense. That Tillis chose a book — a medium of reflection — to name this particular vote suggests the burden of it has only grown with time.

The statement carries implications beyond one senator's conscience. It surfaces broader questions about how Republicans evaluate executive nominees and whether the confirmation process itself is functioning as it should. For colleagues who voted alongside Tillis, the admission may quietly invite their own reckonings. Hegseth's position is unchanged, but the confirmation that placed him there continues to echo among those who made it possible.

Senator Thom Tillis of North Carolina has written in a forthcoming book that his vote to confirm Pete Hegseth as Secretary of Defense stands as the single greatest regret of his career in public service. The admission, coming years after the contentious confirmation process, represents a stark reversal from the moment Tillis cast his ballot in favor of Hegseth's appointment to lead the Pentagon.

Hegseth's path to the Defense Secretary position had been marked by significant controversy. Questions about his military background, his statements on various policy matters, and concerns about his overall readiness for the role had animated debate both within Republican circles and across the broader Senate. Despite these reservations circulating among some colleagues, Tillis voted to confirm him.

The senator's decision to characterize that vote as his deepest professional regret carries weight precisely because it comes from someone who was in a position to shape the outcome. Tillis, a member of the Republican majority at the time, had the power to vote either way. His choice to support Hegseth was therefore a deliberate act, one he now views with considerable remorse.

This kind of public recanting is uncommon in Senate politics, where members typically defend their votes or move forward without dwelling on past decisions. The fact that Tillis felt compelled to address this vote in a book—a format that suggests reflection and intentionality—suggests the weight of the decision has only grown heavier with time. Whether his concerns have been vindicated by Hegseth's actual performance in office, or whether Tillis simply came to believe he made an error in judgment, the statement amounts to a significant acknowledgment of doubt.

The revelation also speaks to broader tensions within the Republican Party over executive appointments and the standards by which senators evaluate nominees. Tillis's regret implies that the confirmation process itself, or his role in it, fell short of what he now believes it should have been. For other Republicans who voted similarly, the statement may prompt their own reckonings with that decision.

Hegseth remains in the position, and Tillis's regret does not change that fact. But the senator's willingness to name his vote as his career's greatest mistake signals that the confirmation battle, though concluded, continues to reverberate among those who participated in it. The book will likely draw attention to questions about Hegseth's tenure and whether other senators share Tillis's assessment of their own votes.
