US Ambassador to Greece Kimberly Guilfoyle resigns amid mounting allegations over her personal finances, leadership at the US Embassy in Athens and relationships with influential business figures, with fresh reporting raising questions about the circumstances surrounding her departure.
The Daily Mail reports that Guilfoyle, 57, was asked to resign after US President Donald Trump expressed dissatisfaction with negative coverage of her lifestyle and conduct. The ambassador announced her departure while insisting the allegations against her were false.
The latest report alleges that Guilfoyle approached several wealthy Greek businessmen in mid 2025 seeking a $250,000 loan to help pay for a luxury Mercedes G Wagon.
Four sources described by the Daily Mail as Greek and US State Department insiders with direct knowledge of the matter claim the approaches took place as Guilfoyle was preparing to assume her diplomatic post.
According to the newspaper, she did not receive the money she sought.
The allegations add to scrutiny already surrounding the outgoing ambassador following a Wall Street Journal report about messages allegedly showing her seeking help from Republican donor Eric Deters to cover a $100,000 American Express bill.
Guilfoyle’s lawyer has disputed the authenticity of the messages and denied wrongdoing.
New Allegations Over Luxury Car Loan
The Daily Mail reports that Guilfoyle approached wealthy Greek businessmen about financing the Mercedes G Wagon, with the alleged requests raising questions about her financial affairs before she took up the ambassadorship.
The newspaper notes that the vehicle was not listed in her mandatory federal financial disclosure forms. However, the report identifies a separate declared liability for a boat advance valued between $100,000 and $250,000, with Azure Funding listed as the creditor.
The distinction is important. The reported G Wagon loan requests have not been established as a formal debt, and the available material does not establish that Guilfoyle received the money.
The allegations have emerged alongside questions about the financial disclosures and vetting of ambassadorial nominees.
The earlier Wall Street Journal investigation examined messages allegedly showing Guilfoyle asking Deters to settle an American Express bill before her Senate confirmation hearing. The newspaper reported that the messages suggested she linked financial assistance with access to senior administration figures.
Guilfoyle’s legal representative, Jesse Binnall, has challenged the authenticity of the messages. The dispute also involves claims about payments for public appearances, which Deters denies owing.
Neither set of allegations should be treated as a finding of misconduct.
State Department Investigation Under Scrutiny
The new reporting follows earlier Daily Mail claims that the US State Department’s Office of Inspector General opened an investigation after complaints about Guilfoyle’s leadership and the alleged use of embassy resources and corporate hospitality.
The newspaper says the investigation could attract renewed attention following her departure, as individuals with information may become more willing to come forward.
The allegations reportedly include complaints about staff management, requests for complimentary hospitality and the handling of relationships with business figures.
The Daily Mail also reports that Guilfoyle dismissed a veteran Greek economic adviser who had served several US ambassadors, leaving other embassy staff concerned about the loss of institutional experience.
These claims have not been independently established in the material provided for this report.
Guilfoyle has rejected the allegations in broad terms, declaring that she intends to defend her reputation.
Reports of Diplomatic Isolation in Athens
The controversy has also raised questions about Guilfoyle’s relationships with Greek officials and senior figures in Washington.
According to the Daily Mail, Greek government officials were reluctant to meet Guilfoyle in the period before her departure.
The newspaper further reports that she was excluded from a key one on one meeting between US Secretary of State Marco Rubio and Greek Prime Minister Kyriakos Mitsotakis during Rubio’s visit to Athens the previous week.
The report also alleges that Alexandros Exarchou, chairman and group chief executive of AKTOR Group, was not permitted to attend an official state dinner associated with Rubio’s visit.
The newspaper describes Exarchou as a key local ally of Guilfoyle and reports previous allegations that she promoted business interests connected to his construction and energy group.
Those claims raise questions about the boundaries between diplomatic engagement and commercial interests. However, the available reporting does not establish that Guilfoyle improperly intervened on behalf of the company.
The Daily Mail also describes a tense relationship between Guilfoyle and Rubio during the visit, despite the pair being photographed greeting each other warmly on the tarmac.
These accounts are attributed to unnamed sources and have not been independently verified.
Questions Over a Possible JD Vance Visit
The report also says Guilfoyle had been telling contacts in Athens that US Vice President JD Vance would make an official state visit to Greece in February 2027.
However, Vance’s team told the Daily Mail that it had no travel plans for 2027 to announce at that time.
The newspaper reports that Vance had previously described questions about the allegations against Guilfoyle as hypothetical, while expressing dissatisfaction with the surrounding controversy.
The reported disagreement over a possible visit adds another dimension to questions about the ambassador’s standing in Washington as her tenure came to an end.
Guilfoyle Vows to Fight Allegations
In her resignation statement on X, Guilfoyle presented her tenure as a success for the Trump administration’s energy, defence and economic agenda.
She highlighted efforts to expand US liquefied natural gas exports to Europe, advance the Vertical Corridor energy route, strengthen defence cooperation with Greece and promote American investment in Southeast Europe.
She also thanked Trump and Rubio for the opportunity to serve, praised the Greek people for their hospitality and reaffirmed her support for the administration’s America First agenda.
Addressing the allegations, Guilfoyle wrote: “These allegations are false, and I intend to vigorously defend my name, my reputation, and my integrity.”
She added that she would not allow the accusations to define her decades of public service.
White House Press Secretary Katie Zacharia confirmed that Guilfoyle had been asked to resign, according to the Daily Mail, while publicly describing her as a valuable member of the team and wishing her well.
The resignation marks a significant turn for a diplomat whose appointment attracted attention because of her relationship with Donald Trump Jr., the president’s eldest son. The couple were previously engaged before he began a relationship with Bettina Anderson, whom he later married.
Guilfoyle’s departure leaves questions about the status of the reported inspector general investigation, the outcome of the disputed financial allegations and the future of US diplomatic representation in Athens.
For now, the claims against the former ambassador remain contested. Guilfoyle denies wrongdoing and says she intends to defend her name, while the reports about her finances, management and diplomatic relationships continue to draw scrutiny.
