A former Trump donor has gone public with claims that the U.S. ambassador to Greece took hundreds of thousands of dollars from him in exchange for promised access to the administration — bad news for Kimberly Guilfoyle, who Trump now says may be fired.

• Ohio lawyer Eric Deeters says he paid Guilfoyle $300,000 over several years and got nothing in return.
• He wanted help pushing the Justice Department to extradite a doctor accused of performing hundreds of unnecessary spinal surgeries, including on children, plus help with an IRS dispute over an old tax deduction.
• He says Guilfoyle asked for another $100,000 to pay off a credit card bill a week before her confirmation hearing, and suspects she made similar asks of others.
• Much of the messaging moved to the encrypted app Signal, and he is now suing her for calling the texts fake and labeling him a blackmailer.
• He says he soured on Trump over the unanswered extradition request, high gas prices, and the memecoin — arguing Trump only courts billionaires and officials who can boost him.

Outlook: Trump has said firing Guilfoyle is under consideration, and the threatened lawsuit would keep the story alive well past any dismissal.
