Sen. John Barrasso (R-Wyo.), the Senate Majority Whip, on Sunday voiced alarm over recent press reports detailing financial irregularities involving U.S. Ambassador to Greece Kimberly Guilfoyle, signaling that a formal inquiry is likely.
Speaking on CBS's Face the Nation, Barrasso told host Margaret Brennan that the disclosures are deeply concerning. "Well, what we've seen in the reports is very troubling. It's concerning. And I'm sure there's going to be an investigation. I would assume the State Department would be conducting that," he said.
Barrasso added that the Senate Foreign Relations Committee would also exercise oversight. "I know that 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 — what is found, and it is quite a bit of concern," he said.
The remarks come after the Wall Street Journal reported Thursday that Guilfoyle asked a Trump donor, Eric Deters, to settle a $100,000 credit card bill, providing instructions for a wire transfer that she claimed would leave no trace. "It won't show up anywhere if you wire money to American Express," Guilfoyle wrote on Signal in July 2025, according to messages reviewed by The Hill. At the time, she worried the conversations could jeopardize her confirmation.
Subsequent reporting Saturday indicated that senior Trump administration officials have been discussing Guilfoyle's future in her post, with a decision from President Trump expected soon. The Journal also reported new allegations that wealthy Greek businessmen funded Guilfoyle's luxury travel while she used her diplomatic position to advance their commercial interests. The Hill has reached out to the White House for comment.
The controversy has already drawn attention from other administration figures. Vice President Vance has said that if the allegations prove true, Guilfoyle must face consequences, while President Trump has dismissed the debt scandal as "too bad." The situation has also highlighted policy and political fault lines within the administration, particularly regarding Secretary of State Marco Rubio's involvement in the Greek trip.
Barrasso's public concern underscores the political sensitivity of the matter as Republicans hold a narrow majority in the House and face a challenging electoral landscape. The ongoing scrutiny could complicate the administration's foreign policy agenda and raise questions about ethical standards among its appointees.
As the story develops, the State Department has not yet announced an official investigation, but Barrasso's remarks suggest that congressional oversight is likely to intensify. The public, he said, deserves transparency about the findings.
