Donald Trump said Sunday he has decided against testifying for a second time at his New York civil fraud trial, posting on social media a day before his scheduled appearance that he “very successfully & conclusively” testified last month and saw no need to do so again.

The former president, the leading contender for the 2024 Republican nomination, had been expected to return to the witness stand Monday as a coda to his defense against New York Attorney General Letitia James ' lawsuit.

James, a Democrat, alleges Trump inflated his wealth on financial statements used in securing loans and making deals. The case threatens Trump’s real estate empire and cuts to the heart of his image as a successful businessman.

“I will not be testifying on Monday,” Trump wrote in an all-capital-letters, multipart statement on his Truth Social platform less than 20 hours before he was to take the witness stand.

“I have already testified to everything & have nothing more to say,” Trump added, leaving the final word among defense witnesses to an accounting expert hired by his legal team who testified last week that he found “no evidence, whatsoever, for any accounting fraud” in Trump’s financial statements.

A Trump spokesperson did not immediately respond to questions about his decision.

The decision was an abrupt change from Trump’s posture in recent days, when his lawyers said he was insistent on testifying again despite their concerns about a gag order that has cost him $15,000 in fines for disparaging the judge’s law clerk.

“President Trump has already testified. There is really nothing more to say to a judge who has imposed an unconstitutional gag order and thus far appears to have ignored President Trump’s testimony and that of everyone else involved in the complex financial transactions at issue in the case,” Trump lawyer Christopher Kise said Sunday.

Trump’s decision came days after his son, Eric Trump, ditched his return appearance on the witness stand. Trump said on social media that he’d told Eric to cancel. It also follows Trump’s first trip back to court since he testified in the case on Nov. 6. Last Thursday, he watched from the defense table as the accounting professor, New York University professor Eli Bartov, blasted the state’s case and said Trump’s financial statements “were not materially misstated.”

Trump’s cancellation caught court officials by surprise. Without Trump on the witness stand, the trial will be on hold until Tuesday, when Bartov will finish his testimony. State lawyers say they’ll then call at least one rebuttal witness.
