The United States Ambassador to Greece, Kimberly Guilfoyle, has been thrust back into the spotlight after an investigation by The Wall Street Journal, according to which she boasted of close ties to two wealthy Greek businessmen, who allegedly financed her private jet trips and luxury hotel stays.
According to the American newspaper, which cites people who heard the conversation and an audio recording provided by her, Guilfoyle spoke about these connections at the World Economic Forum in Davos in January 2026. At the time, she was trying to secure an invitation to a dinner hosted for Eric Trump, the son of US President Donald Trump, as her name was not included on the guest list.
"I know, I can bring the world to you. Which you deserve," Guilfoyle is heard saying in the recording. At another point in the conversation with an American businessman, she says: "I'll make you a lot of money."
The ambassador reacted angrily to the lack of an invitation, saying that the event organizer should have treated her with more respect. In the end, Guilfoyle managed to secure a seat at the dinner at the last minute. The head of the Greek House Davos organization, Irene Vantaraki, said that her team had to manage a difficult situation that involved several important guests. According to her, Guilfoyle was polite and discreet and left the event early.
In the recording published by The Wall Street Journal, Guilfoyle admits to having traveled to Davos on the private jet of Alexandros Exarchou, the CEO of the Greek construction company Aktor Group.
The newspaper previously reported that Guilfoyle had encouraged governments, including those of Albania and Bulgaria, to cooperate with Exarchou and buy billions of dollars worth of American natural gas through his company. In the recording, she describes the businessman as part of her inner circle.
Another businessman who reportedly facilitated the ambassador's travels is Greek shipping magnate Nikolas Tsakos. Guilfoyle said he planned to fly to Paris to attend his wife's fashion show. She also mentioned spending part of the holiday season with the couple in the luxury resort of Gstaad, Switzerland.
According to people quoted by the newspaper, Tsakos also covered the bill for Guilfoyle's stay at the luxurious Four Seasons George V hotel in Paris. The ambassador then posted about 20 photos on Instagram from the fashion event, where she appeared in several dresses by famous designers, including photos with Tsakos.
Tsakos and his wife did not respond to requests for comment, while Aktor Group, through lawyers, declined to comment. The company's legal representatives have denied that Guilfoyle improperly promoted its business interests.
A spokesman for the U.S. Embassy in Athens said Guilfoyle had complied with State Department guidelines on ethics and gift declarations. He called the allegations unfounded and an attempt to distract from the ambassador's work in Greece and the Eastern Mediterranean.
The new revelations come as the State Department is investigating whether Guilfoyle received gifts or favors from private businessmen. According to The Wall Street Journal, Trump administration officials are discussing the possibility of removing her from office, with a decision expected from the US president.
The ambassador had previously faced other charges after the publication of messages she allegedly sent to a Donald Trump donor, asking for $100,000 to pay off her American Express card. According to the newspaper, in exchange, she offered to help draw the donor's personal legal and tax issues to the attention of the US administration. Guilfoyle's lawyer has disputed the authenticity of the messages.
The developments have prompted a backlash from Democrats in the US Congress. Gregory Meeks, the top Democrat on the House Foreign Affairs Committee, called for an immediate investigation to determine whether the ambassador violated federal laws against bribery and corruption. Robert Garcia, the Democratic chairman of the House Oversight Committee, also requested financial records and communications with US government officials.
Vice President JD Vance said the allegations should be investigated before conclusions are drawn. "Let's see what the truth is. And, of course, if something wrong has happened, people need to face the consequences," he said.
