Senator John Barrasso, the Senate Majority Whip, said on Sunday that the recent reports about U.S. Ambassador to Greece Kimberly Guilfoyle’s finances are “very troubling” and that an investigation is likely. He added that he would expect the State Department to look into the matter. Barrasso’s comment comes after a series of news articles and a congressional hearing that raised questions about Guilfoyle’s wealth and possible ties to Greek business interests.

Guilfoyle was appointed by President Biden in 2022 after a career as a Fox News host and a long‑time friend of the president. Her financial disclosures, released to the public in 2023, list a net worth of more than $50 million and reveal significant holdings in companies that do business with the Greek government. Critics say these connections raise the possibility of a conflict of interest, especially as Greece has been a key partner in U.S. efforts to counter Russian influence in the Mediterranean. The reports also point to undisclosed gifts and a lack of transparency in her asset disclosures, prompting calls from some lawmakers for a full audit.

The House and Senate committees on foreign affairs have called for a review, and the State Department has announced that it will conduct an internal investigation. Democratic lawmakers have urged a swift response, while Republicans have framed the issue as a test of the administration’s vetting process. Some Greek officials have expressed concern that the controversy could strain diplomatic relations, though they have not yet issued a formal statement. The Biden administration has not yet responded to the allegations, but the White House is likely preparing a statement that will address the integrity of the ambassadorial appointment process.

If the investigation finds violations of U.S. law or State Department policy, Guilfoyle could be asked to resign or could face a formal reprimand. The outcome will also feed into a broader debate about the vetting of political appointees and the role of personal wealth in diplomatic positions. The next few weeks will see whether the Senate will hold a confirmation hearing on Guilfoyle’s successor or whether the administration will appoint a new ambassador to Greece without delay. The case highlights the growing scrutiny of public officials’ financial ties and the potential impact on U.S. foreign policy in a volatile region.
