A former Fox News star who spent years inside President Trump’s political and family orbit is reportedly sitting on a private “burn book” filled with secrets.

The woman at the center of the claim is Kimberly Guilfoyle, the former fiancée of Donald Trump Jr. who resigned Tuesday as U.S. ambassador to Greece.

But there is a major divide between what unnamed insiders are alleging and what Guilfoyle herself is saying in public.

Her own statement sounded nothing like a declaration of war against the Trump family.

Guilfoyle thanked President Trump and Secretary of State Marco Rubio, called her diplomatic service “the honor of a lifetime,” and pledged that her commitment to the America First movement would continue:

That is why the new report is drawing so much attention.

The Daily Mail reports that some Trump allies worked behind the scenes to preserve Guilfoyle’s diplomatic post because they feared what an angry former insider might reveal after returning to the United States. According to unnamed sources cited by the outlet, Guilfoyle kept a private journal chronicling people, relationships, feuds and conversations from her years close to the family and political operation.

The sources claimed the journal has been nicknamed “The Devil Wears MAGA” and alleged that Guilfoyle could release damaging material after her abrupt departure.

One source described her as someone who knows the people, the secrets and the internal fights after six years in a relationship with Donald Trump Jr. and years as a prominent Trump campaign surrogate.

The Mail also reported that allies viewed keeping Guilfoyle overseas as a way to avoid a bitter break with someone who had been deeply embedded in Trumpworld.

Their alleged concern was that she could connect personal details to the larger political operation and turn private history into a public spectacle.

Those are explosive claims.

They are also unverified.

No diary has been produced publicly, and Guilfoyle has not confirmed that it exists.

There is no public evidence showing that she has threatened President Trump or his family, and the report rests on unnamed sources describing private conversations and fears.

That distinction matters, especially because Guilfoyle’s public message remains supportive of Trump.

The backdrop to the story, however, is very real.

President Trump told reporters that Guilfoyle was leaving because he did not like what he had been reading about her conduct. He also rejected the suggestion that her former engagement to his son made her a member of the family.

Trump gave that explanation on camera:

The removal followed a run of allegations involving Guilfoyle’s conduct before and during her time in Athens.

CBS News reports that the White House asked Guilfoyle to resign after scrutiny of messages in which Trump donor Eric Deters alleged she asked him to wire $100,000 to her American Express account before her Senate confirmation hearing. Deters said he had been seeking help obtaining access to administration officials and characterized the request as improper.

Guilfoyle’s attorneys have disputed that account. They said any money discussed was legitimate compensation for speaking appearances and other work completed before her nomination, not payment in exchange for influence.

Her legal team has also denied separate allegations concerning private travel and said she followed State Department guidance.

Guilfoyle has called the accusations false and said she intends to defend her name, reputation and integrity.

The Associated Press reports that Guilfoyle submitted her resignation after the White House publicly asked her to leave. The outlet said the decision followed allegations involving a host-country official, gifts and services, and an alleged offer to use her influence in connection with payment of a personal credit-card bill.

The White House announced the request during press secretary Katie Zacharia’s first formal briefing. Guilfoyle then released her own statement saying that her time as ambassador was ending while her commitment to President Trump, America First and the country would continue.

AP also placed the departure in a rapid timeline: public reporting had raised questions about Guilfoyle’s future, Trump said the administration was reviewing the matter and was “not happy,” and the resignation followed the next day.

The outlet noted that Guilfoyle denied wrongdoing and that her lawyers challenged the accounts surrounding her conduct and finances.

AP’s breaking alert confirmed the resignation as the story was unfolding:

Guilfoyle had one of the shortest and most closely watched diplomatic tenures of the second Trump administration.

Trump nominated her in December 2024. The Senate confirmed her in September 2025, and she formally presented her credentials in Athens that November.

She became the first woman to serve as U.S. ambassador to Greece.

Her appointment followed the end of her engagement to Donald Trump Jr., a relationship that had made her a fixture at campaign events, private gatherings and Republican fundraisers.

That history makes the alleged journal politically combustible even if its contents never emerge.

Someone who spent years that close to a presidential family would naturally have seen personal tensions, political disagreements and private moments that never reached the public. That does not prove she documented them, and it certainly does not prove she plans to weaponize them.

For now, the public record shows two competing pictures.

Unnamed insiders are portraying a furious former confidante who may be ready to settle scores.

Guilfoyle is publicly thanking President Trump, defending her own record and promising continued loyalty to America First.

Until the alleged “burn book” appears—or Guilfoyle addresses the claim directly—the most sensational part of this story remains just that: an allegation.

But the nervousness described by people around Trump tells its own story.

Washington understands the value of proximity. It also understands the danger when someone who once had it walks away with a long memory.
