Kimberly Guilfoyle Resigns as U.S. Ambassador to Greece

Kimberly Guilfoyle resigned as U.S. ambassador to Greece on Tuesday, two people familiar with the matter confirmed to NBC News, ending a tenure that began with her 2025 Senate confirmation and closes amid a State Department inspector general's investigation into her conduct.

Why Did Guilfoyle Resign as Ambassador to Greece?

The resignation followed a request from the White House. At her first press briefing, new press secretary Katie Zacharia told reporters, "We have asked Ambassador Guilfoyle to resign. She has been a wonderful asset to the team, and we wish her well," according to NBC News. Guilfoyle, 57, confirmed the move in a post on X, calling the posting "the honor of a lifetime" and writing that allegations against her "are false," vowing to "vigorously defend my name, my reputation, and my integrity."

What Allegations Triggered the State Department Probe?

The inspector general's inquiry began after The Wall Street Journal reported allegations that Guilfoyle bragged about ties to Greek tycoons she said funded luxury trips for her, citing people who said they heard the conversation and an audio recording, NBC News reported. NBC News said it has not independently confirmed those allegations.

A separate claim surfaced this month from Trump donor Eric Deters, who told NBC News that Guilfoyle asked him to cover a $100,000 American Express bill in the days before her 2025 Senate confirmation hearing in exchange for access to senior administration officials.

"She was so desperate for that $100,000. It was a quid pro quo," Deters told NBC News.

What Did the White House and Trump Say?

Speaking to reporters Tuesday, President Trump said Guilfoyle "was doing a good job, but we didn't like what we were reading," adding that he had not spoken with her directly, per NBC News. The president's comment did not specify which reporting prompted the decision, and the White House did not detail the inspector general's findings in Tuesday's briefing.

What Happens Next for the U.S. Embassy in Athens?

NBC News's report did not name a successor or interim chargé d'affaires for the Athens post. Guilfoyle, the former fiancée of Donald Trump Jr. and a onetime Fox News personality who served as a top Trump campaign surrogate, had held the ambassadorship since her 2025 confirmation.
