U.S. Ambassador to Greece Kimberly Guilfoyle pressed a major Trump donor to wire $100,000 directly to American Express to cover a personal credit card bill, according to text messages reviewed by The Wall Street Journal and reported this week.

The July 3, 2025, messages on the encrypted Signal app came six days before Guilfoyle's Senate Foreign Relations Committee hearing for the Greece post. In one exchange, she wrote to Kentucky businessman and former congressional candidate Eric Deters, "Honey please I need you to get this done for me today," followed by a praying hands emoji and a PDF containing payment instructions from the credit card company.

"You could just send it here," she added. "It won't show up anywhere if you wire money to American Express that's all that will show. Please."

Deters, who had offered Guilfoyle up to $1 million if she helped him gain access to Trump administration officials regarding his tax and legal matters, declined the request. He replied that the urgent ask would not work and that he could not make the payment without risking his marriage.

The donor had already paid Guilfoyle approximately $300,000 over several years for speaking engagements without receiving favors in return, according to messages cited in the reporting. Guilfoyle had forwarded him notes she sent to then-IRS Commissioner Billy Long as part of efforts to assist him.

An attorney for Guilfoyle disputed the authenticity of the messages. A U.S. Embassy official in Greece defended her record, pointing to her Senate confirmation on a 51-47 vote in September 2025 and her commitment to integrity.

The exchange occurred amid broader discussions between the two about potential assistance with Deters' issues in the new Trump administration. Guilfoyle had reportedly complained to associates about being broke following the end of her engagement to Donald Trump Jr.

Secretary of State Marco Rubio declined to address the specific claims during a recent visit to Greece, criticizing media reliance on unverified sources.

The story emerged from hundreds of messages, emails, and letters examined by the Journal and has drawn renewed attention this week as details circulated across multiple outlets.
