President Donald Trump and Secretary of State Marco Rubio are considering firing US Ambassador to Greece Kimberly Guilfoyle following a growing series of reports alleging improper and possibly illegal conduct before and during her tenure in Athens.

A senior US official said Sunday that Trump and Rubio are “extremely pissed off” over Guilfoyle’s reported conduct. The official said they would likely decide what action to take this week following Monday’s Columbus Day holiday.

The official spoke on condition of anonymity to discuss internal deliberations. Rubio was said to be particularly angry because he had visited Athens just last week, where Guilfoyle attended most, if not all, of his events and greeted him with a bear hug while the allegations were swirling.

The Wall Street Journal has published a series of stories detailing questionable conduct by Guilfoyle. The allegations include threatening a host country official, accepting improper gifts and services, and offering to use her influence within the administration in exchange for payment of a large credit card bill.

Guilfoyle has not directly addressed the reports. Her lawyer has maintained that she did nothing wrong, while the US Embassy in Athens has tacitly expressed support for the ambassador.

Rubio initially defended Guilfoyle after the first report, but he has since declined to publicly address the expanding allegations. On Wednesday, he said, “Our ambassador has been a strong ambassador here.”

Another report appeared late Wednesday. Before leaving Athens on Thursday, Rubio criticized journalists for questioning him about allegations he said he could not confirm, while Guilfoyle watched as she saw him off.

The senior official said Rubio’s frustration increased as the reports multiplied. Vice President Vance also brushed aside questions as hypothetical, though he acknowledged that he did not love what was being reported about Guilfoyle’s spending and expenses.

The controversy follows Daily Mail reports concerning Guilfoyle’s Champagne demands while serving as ambassador and leaked text messages about the collapse of her engagement to Donald Trump Jr. Those reports added another layer to the scrutiny surrounding her conduct in Greece.

A second US official, also speaking anonymously about personnel matters, said the State Department inspector general is looking into the allegations. Those claims first began appearing in the Journal late last month and have continued to multiply.

The second official could not say whether a formal inspector general investigation had started. Inspectors general sometimes conduct informal inquiries into complaints against staff members that do not become full investigations or produce disciplinary action.

The State Department has declined to comment on a potential inspector general investigation. Democratic lawmakers Rep. Gregory Meeks of New York, Sen. Jeanne Shaheen of New Hampshire, and Rep. Robert Garcia of California have called for an investigation into Guilfoyle.

The Journal’s first report alleged that Guilfoyle told guests at a reception that the US could undermine the Greek government if it chose. It also said she promoted one Greek construction and energy company’s business interests and allowed its lobbyist into private diplomatic meetings.

During Rubio’s Athens visit, the Journal cited text messages in reporting that Guilfoyle asked a Trump donor and supporter to pay a $100,000 credit card bill shortly before her confirmation hearing. She allegedly promised the donor access to administration officials if he paid it.

The Journal later reported that Guilfoyle became enraged after she was not invited to a Greek-themed event at the World Economic Forum in Davos, Switzerland. According to the report, she demanded to attend while boasting about luxury travel to France with energy company executives.

The Daily Mail also reported that Guilfoyle had alienated staff at the US Embassy in Athens and pushed the boundaries of conduct expected from the top US representative to Greece. The report described complaints concerning allegedly tyrannical leadership, lavish corporate perks, and a Champagne-filled lifestyle.

Guilfoyle arrived in Greece following her public split from Trump Jr., whom she began dating during Trump’s first term. After photographs emerged of Trump Jr. with Palm Beach socialite Bettina Anderson, Trump announced in December that Guilfoyle would become ambassador to Greece.

Since arriving, the former Fox News personality has approached the position with her characteristic flair. She has mixed meetings with presidents and ministers with appearances at fashion shows and art galas, while posting to nearly two million Instagram followers.
