Advisers to President Donald Trump reportedly made behind-the-scenes efforts to preserve Kimberly Guilfoyle’s position as US ambassador to Greece before she was asked to step down Tuesday, according to sources who spoke to the Daily Mail. Her departure followed allegations of improper, and potentially unlawful, conduct during her time in Athens.
People familiar with the situation said Trump allies had hoped to keep his former fiancée in the diplomatic role, fearing that a return to the United States could leave her embittered and willing to disclose private information about the Trump family.
Following her resignation, sources claimed Guilfoyle has maintained a private “burn book” containing details about the Trumps and could sever her remaining ties to the family after her sudden fall from favor.
Insiders have reportedly nicknamed the alleged diary “The Devil Wears MAGA” and said Guilfoyle may threaten to make parts of it public.
Guilfoyle, 57, spent much of her six-year relationship and engagement to Donald Trump Jr. close to the president’s inner circle. She attended private family events and was familiar with personal discussions among those around the Trump family.
Although Guilfoyle and Trump Jr. ended their engagement in 2024, she remained connected to the family after being named ambassador to Greece. Her roughly 11 months in the post later came under intense scrutiny after a Daily Mail investigation examined her lavish lifestyle and reported allegations of misconduct.
The White House confirmed Tuesday that Guilfoyle had been asked to resign. Reports said Trump and Secretary of State Marco Rubio were deeply angered by the conduct attributed to her, prompting an investigation by the State Department’s Office of Inspector General the previous week.
While allies of the president are said to welcome her exit from the diplomatic post, sources warned that the Trump family may still face repercussions from the ambassador’s departure.

“Having her back in America would be a nightmare. Kimberly knows where the bodies are buried. She knows the people, the secrets, the fights, the relationships,” one source told the Daily Mail.
“Nobody wants an angry Kimberly back home with nothing to lose.”
Her removal from office could now create fresh tension for Trump Jr., other members of the Trump family and the political allies who have worked closely with them.
Guilfoyle responded publicly several hours after the White House announcement, confirming that she was leaving the position while strongly rejecting the allegations made against her.
In a lengthy statement posted on X, she insisted the accusations were ‘false’ and vowed to ‘vigorously defend my name, my reputation, and my integrity.’
“I have dedicated my professional life to fighting for justice, standing up for what is right, and defending the values that make America exceptional,” Guilfoyle said. “I will not allow false accusations to define my decades of public service.”
The MAGA supporter and former Fox News co-host described her time as ambassador as “the honor of a lifetime.”
Before Tuesday’s decision, individuals familiar with the matter said efforts were underway to shield Guilfoyle, who dated Trump Jr. for six years before he ended their relationship and later married Palm Beach socialite Bettina Anderson.

“Kimberly knows everything. She was way inside that family and political operation for years,” one insider told the Daily Mail.
Another source said: ‘Keeping Kimberly happy keeps Kimberly quiet.’
Don Jr’s friends have expressed relief that he escaped Guilfoyle’s orbit, telling the Daily Mail they had serious concerns about the relationship.
One source familiar with their engagement told the Daily Mail that Don Jr never actually proposed to Guilfoyle and that she had procured and started wearing her own engagement ring during the relationship – ultimately prompting an engagement announcement that Guilfoyle herself released.
The Daily Mail has contacted Don Jr for comment.
Ironically, it was Don Jr’s romancing of Anderson while still officially engaged to Guilfoyle, which was exclusively revealed by the Daily Mail – that eventually saw the latter pack her bags for Athens.

Up until Tuesday’s decision, some in the know scrambled behind the scenes to protect the woman Don Jr. dated for six years before dumping her for his new wife
Our exclusive photo of Don Jr and Anderson on an intimate brunch date at a ritzy Palm Beach diner on August 17, 2024 was the first public clue that he was looking elsewhere for romance.
The 48-year-old and Anderson, 39, were spotted canoodling at the Honor Bar, with the Florida beach town’s ‘smitten’ It Girl seen reaching over to plant a kiss on Don Jr’s lips three times.
Nearly three months later, on December 10 of that year, the Daily Mail published exclusive photos of the soon-to-be first son and his new love walking hand-in-hand after dinner at a swanky Palm Beach eatery – serving as incontrovertible proof that they were an item.
Before publication that day, the Daily Mail asked one of Don Jr’s representatives for a comment about the photos and the relationship.
Hours later, then President-elect Donald Trump suddenly announced he had nominated Guilfoyle for the ambassador role – some 5,800 miles away.
‘Kimberly wasn’t sent to Greece just because of her skills,’ a source tells us amid the latest controversy.
‘It also solved a complicated personal problem. Having her thousands of miles away worked for everyone.’
Explosive further details about the Don Jr and Guilfoyle’s relationship breakdown were recently revealed in text messages between Guilfoyle and Republican donor Eric Deters and obtained by the Daily Mail.

The messages were exchanged after a Patriots Day Freedom Fest on September 14, 2024, which was organized by Deters and attended by the couple, whose relationship was rapidly unraveling.
Two days after the Daily Mail brunch story was published on September 15, Deters texted Guilfoyle: ‘You doing OK? Saw the Daily Mail report. I have that app. I could tell Saturday you were hurting.’
Guilfoyle snapped back, calling the story ‘fake news’ and insisting: ‘I wasn’t hurting wtf.’
However, it didn’t take long for tension to reveal itself.
In another, undated exchange, Guilfoyle took a jab at Anderson, texting: ‘I was having a f**king great time Saturday and we had a f**king amazing time when we got home… that’s nonsense.
‘It’s all lies, but she’s a cloud chasing horror that plays the story in the Daily Mail to get attention,’ Guilfoyle wrote, falsely claiming the new Mrs Trump sent her own bikini shots to be included in the report.
Don Jr and Guilfoyle had been living at a waterfront mansion in Jupiter, Florida, that they purchased together in 2021 for $9.7 million. The president’s son bought her share in July this year for $8.5 million.
After the ambassador announcement, Don Jr swiftly moved on with his romance to Anderson – with the Daily Mail exclusively revealing their civil wedding in Palm Beach last May, followed by a lavish celebration on the island of Little Pipe Cay in the Bahamas.

Meanwhile, Guilfoyle took up her position in Greece on November 4, 2025 and began a controversial reign that now sees serious allegations against her.
Five sources have confirmed to the Daily Mail that a formal Department of State Office of Inspector General (OIG) probe has been opened into the ambassador and her US embassy.
Three of them claim the Inspector General is looking into allegations of potential substance abuse, use of private planes and helicopters, a close relationship with an energy and construction company, and improper acceptance of gifts.
Guilfoyle’s lawyer Jesse Binnall had previously declined to comment on the probe when asked prior, telling the Daily Mail that the ambassador won’t comment on ‘internal matters’ as a ‘standard policy.’
‘Any implication of wrongdoing by the Ambassador is unsupported,’ he added and referred the Daily Mail to the State Department OIG.
The probe follows extensive Daily Mail reporting on the ambassador’s lavish lifestyle, detailing high-flying luxury travel, parties with Greek billionaires, an unpaid dining bill and close ties to energy lobbyist Christos Marafatsos.
Text messages obtained by the Wall Street Journal also show Guilfoyle pressed Deters to pay her $100,000 American Express bill days before her Senate confirmation hearing in July 2025.
Deters, a former congressional candidate in Kentucky, alleged to the outlet that the ambassador offered access to senior Trump administration officials and promised to help him with legal and tax issues in exchange for the money. He did not pay the bill, according to the WSJ.

Additionally, sources have told the Daily Mail that there is a ‘toxic workplace’ climate inside the Athens mission.
‘When you are a political appointee like she is, you have to do your very best to perform inside the system walls and she is doing the complete opposite of that,’ said one who is familiar with the alleged OIG investigation.
Greek sources allege Guilfoyle has had sporadic outbursts and threatened subordinates with immediate termination. On several occasions, she reportedly snarled to embassy workers: ‘F**king get it done or you’re f**king fired.’
Following her Senate confirmation last September, insiders urged Guilfoyle to be on good behavior, cautioning that an assignment amid Aegean islands and endless summers wasn’t a green light for nonstop partying.
Nevertheless, she reportedly jetted into Athens on a billionaire’s private jet and set up several large welcome parties for herself, including one headlined by a famous Greek pop star, using the State Department email for RSVPs.
By July this year, Guilfoyle was spotted sipping bubbly and nibbling grapes at Nammos – the ultra-exclusive jet-set club on Mykonos’ Psarou Beach.
The very next day, she jetted off to Paris for Fashion Week.
That same month, Trump bypassed Greece entirely on his return flight from the NATO summit in Turkey, leaving Guilfoyle’s promises of a presidential visit unfulfilled.

Guilfoyle’s attorneys, David Schwartz and Jesse Binnall, denied the ambassador had done anything wrong in a statement late Sunday.
They said the money she was seeking from Deters was for services such as public appearances and speaking engagements which took place prior to her nomination and for which she had not been paid.
The lawyers also rejected allegations of impropriety relating to travel on private planes, saying Guilfoyle ‘sought, obtained and followed State Department guidance.’
They added: ‘Ambassador Guilfoyle has served and will continue to serve with integrity, honor and distinction.’
The Daily Mail contacted Guilfoyle regarding this story and received no further comment.
