U.S. Ambassador to Greece Kimberly Guilfoyle may soon be the target of a Senate investigation following a bombshell report accusing her of influence peddling.
Guilfoyle is under fire following a Wall Street Journal report that alleged, before she was confirmed as ambassador to Greece, she pushed a top donor to President Donald Trump to clear $100,000 in personal credit card debt.
And a top Senate Republican believes that following that report, an investigation may soon follow. Senate Majority Whip John Barrasso, R-Wyo., said on CBS News’ “Face the Nation” that “what we’ve seen in the reports is very troubling, it’s concerning.”

“And I’m sure there’s gonna be an investigation,” Barrasso said.
“I would assume the State Department would be conducting that,” he continued. “I know the Senate Foreign Relations Committee will have oversight and look into that, as well. But I think the public has a right to know what was found, and it is quite a bit of concern.”
Fox News Digital reached out for comment on a possible investigation to the State Department and Sen. James Risch, R-Idaho, the top Republican on the Senate Foreign Relations Committee.

Guilfoyle, who was recently engaged to Trump’s son Donald Trump Jr. until the two publicly split in 2024, was confirmed by the Senate last year for the post in Athens.
Barrasso’s prediction comes as allegations surrounding Guilfoyle and her time in Athens mount, and as speculation that her time in the role may be coming to an end. The State Department’s Office of Inspector General, the watchdog for the agency, has already opened a probe into Guilfoyle for previous alleged misconduct.
The Daily Mail reported that an investigation was already underway into Guilfoyle’s luxury lifestyle in Greece that included allegations of mistreatment of staff, substance abuse, close ties to an energy and construction company and the improper acceptance of gifts.

The latest claim against her is that she allegedly solicited Trump donor Eric Deters to pay off a $100,000 American Express bill directly to the credit card company, urged him not to leave a paper trail and offered to help him gain access to top administration officials in exchange. Deters said he never made the payment.
In the wake of that report, Trump and Secretary of State Marco Rubio are said to be “extremely pissed off” by Guilfoyle’s alleged conduct and are weighing her removal, The Associated Press reported Sunday, citing a senior U.S. official.

Rubio fired back shortly after the Wall Street Journal reported the allegations, saying, “You guys walk around thinking that because some source told you something, and you reported it, it’s the gospel.”
“It’s not the gospel,” Rubio said. “It’s not the gospel for me. That’s not the way we do things.”
