An expert paid nearly $900,000 to testify in Donald Trump's fraud trial once had his evidence tossed by a New York judge who found it “flatly” contradictory, according to reports and court records.

Evidence from Eli Bartov — an NYU professor paid $877,500 to testify in defense of Trump’s accounting methods — was rejected by the judge in New York Attorney General Letitia James’ case against ExxonMobil in 2019, ABC News reports.

State attorney Louis Solomon made this revelation Tuesday as he cross-examined Bartov in the $250 million civil fraud trial against Trump, his two sons and the Trump Organization, according to the report. Trump has denied wrongdoing.

The judge in the earlier case said Bartov was “unpersuasive” and his testimony was "flatly contradicted by the weight of the evidence," the ruling states.

In that case, Bartov was testifying for the State and against ExxonMobil.
