Kimberly Guilfoyle resigned as U.S. ambassador to Greece on Tuesday after the White House publicly asked her to step down. Her departure follows reports alleging improper conduct before and during her diplomatic service.
The Kimberly Guilfoyle resignation ends a tenure that lasted less than one year. Guilfoyle denies wrongdoing and says she will defend her name and reputation.
Kimberly Guilfoyle Resignation Follows White House Request
White House press secretary Katie Zacharia announced the administration’s decision during a Tuesday briefing.
“We have asked Ambassador Guilfoyle to resign,” Zacharia said. She also described Guilfoyle as an asset to the administration and wished her well.
Guilfoyle announced her resignation on social media less than two hours later. She called her service in Greece “the honor of a lifetime” and thanked President Donald Trump and Secretary of State Marco Rubio.
Trump later confirmed Guilfoyle would leave the position. He told reporters that his administration did not like the reports it had seen about her alleged conduct.
The White House has not announced a replacement. No potential nominees were publicly under consideration Tuesday, according to CBS News.
Reports Allege Financial and Ethical Misconduct
The resignation follows several Wall Street Journal reports about Guilfoyle’s financial dealings and diplomatic activities.
One report alleged that Guilfoyle asked political donor Eric Deters for $100,000 in July 2025. The money would have gone toward an American Express bill before her Senate confirmation hearing.
Deters also wanted Guilfoyle’s help reaching Trump administration officials, according to published accounts. The reports alleged that Guilfoyle offered to use her political connections in exchange for financial assistance.
Deters did not make the payment.
Additional allegations involved private air travel, gifts and services from wealthy Greek businesspeople. Reports also accused Guilfoyle of promoting a Greek company’s interests during official activities.
Other claims included an alleged threat involving a Greek official. None of the allegations has resulted in a publicly announced criminal charge.
Democratic members of the Senate Foreign Relations and House Foreign Affairs committees have requested investigations. The State Department’s inspector general is also reviewing the claims.
However, it remains unclear whether the inspector general has opened a formal investigation. The State Department has declined to comment on that question.
Guilfoyle Denies Allegations
Guilfoyle rejected the allegations in her resignation statement.
“These allegations are false, and I intend to vigorously defend my name, my reputation, and my integrity,” she wrote.
Her attorneys also denied that she sought an improper financial favor. They said the requested money represented unpaid compensation for appearances and speeches completed before her nomination.
The lawyers also defended Guilfoyle’s travel aboard private aircraft. They said she requested State Department guidance and followed federal travel rules before each trip.
Guilfoyle’s attorney has also challenged the authenticity of messages cited in the reports. The U.S. Embassy in Athens previously said she followed government ethics and gift-reporting requirements.
Former Trump Adviser Served Less Than One Year
Trump nominated Guilfoyle for the diplomatic position in December 2024. The Senate confirmed her in September 2025, and she formally began her duties in Greece later that year.
Before entering diplomacy, Guilfoyle worked as a California prosecutor and television host. She later became a prominent Trump campaign adviser and fundraiser.
Guilfoyle was also previously engaged to Donald Trump Jr. Their relationship ended before she began her assignment in Athens.
Her resignation creates a leadership opening at an important U.S. diplomatic post. The United States and Greece maintain close relationships involving defense, energy, trade and regional security.
The White House has not provided a timeline for selecting a new ambassador. Questions also remain about whether congressional or State Department inquiries will continue after Guilfoyle leaves office.
