Kimberly Guilfoyle, U.S. Ambassador to Greece appointed by President Donald Trump, has resigned following mounting allegations of improper conduct before and during her diplomatic tenure in Athens.
The departure follows reports alleging that Guilfoyle sought financial assistance from a Republican donor to settle a $100,000 American Express credit card bill shortly before her Senate confirmation hearing. The allegations have raised questions about ethical standards for senior diplomatic appointees and prompted calls for further scrutiny.
White House Press Secretary Katie Zacharia confirmed that the administration had asked Guilfoyle to leave her post.
“We have asked Ambassador Guilfoyle to resign. She has been a wonderful asset to the team, and we wish her well,” Zacharia said during a White House briefing.
President Trump had expressed dissatisfaction with the reports a day earlier. Asked whether he was considering firing Guilfoyle, Trump told reporters: “Well, we’re looking at it. Yeah, we’re not happy
The controversy intensified after businessman and Trump supporter Eric Deters alleged that Guilfoyle asked him to pay her credit card bill in 2025, before her confirmation.
Deters claimed that he had sought access to senior administration officials and characterised the alleged arrangement as an improper exchange of money for political influence. The allegations, which have since been covered by multiple news organisations.
Guilfoyle has denied wrongdoing. Her attorneys, David Schwartz and Jesse Binnall, said the money she sought related to unpaid fees for public appearances and speaking engagements arranged before her diplomatic appointment.
They also rejected allegations involving private aircraft travel, saying she “sought, obtained and followed State Department guidance and followed the Department’s travel regulations.”
Other published reports have raised concerns about alleged gifts, interactions with Greek officials and possible efforts to promote private business interests. These remain allegations, not established findings of misconduct
A State Department inspector general official was examining the matter, although it remained unclear whether a formal investigation had begun. The State Department declined to comment publicly on a potential inquiry.
Guilfoyle, a former Fox News host and California prosecutor, became a prominent political figure through her association with Trump’s Republican circle and her former engagement to Donald Trump Jr.
Her resignation places renewed attention on diplomatic accountability and U.S.-Greece relations, including cooperation on regional security, energy and European affairs. Washington has not yet announced a successor.
The case also highlights the importance of transparency, ethical oversight and evidence-based reporting when allegations involve senior public officials.
