White House press secretary Katie Zacharia said during her first briefing on Tuesday that Guilfoyle had been asked to resign. "We have asked Ambassador Guilfoyle to resign, she has been a wonderful asset to the team and we wish her well," Zacharia said.
The decision caps a tenure of less than a year for Guilfoyle, one of Trump's longest-standing political allies and the former fiancée of his eldest son, Donald Trump Jr. It came after Trump and Secretary of State Marco Rubio were reported to have grown furious over the allegations.
The most serious claim, first reported by the Wall Street Journal on 8 October, centres on the donor Eric Deters. Citing Signal messages, the paper reported that in July 2025, days before her Senate confirmation hearing, Guilfoyle pressed Deters to pay off a $100,000 American Express bill, assuring him the transfer would not show up anywhere. "Honey please I need you to get this done for me today," she wrote, according to the report.
Guilfoyle offered to use her influence on Deters' tax and legal problems in return, and told him she had contacted the IRS commissioner and the justice department on his behalf. Deters said he paid Guilfoyle about $300,000 over the years without receiving "one favor", and told MS NOW the request "absolutely was a quid pro quo".
The Journal also reported that Guilfoyle accepted improper gifts and services, made an alleged threat to a host-country official, and promoted the interests of Greek company Aktor during official engagements. Her lawyer, Jesse Binnall, said she disputes the authenticity of the messages.
