A spokesperson for New York Attorney General Letitia James described Donald Trump's motion for a mistrial as an effort "to dismiss the truth and the facts."

"Donald Trump is now being held accountable for the years of fraud he committed," the spokesperson said. "He can keep trying to distract from his fraud, but the truth always comes out."

Trump's motion for a mistrial takes aim at Judge Engoron as well as his law clerk, who frequently collaborates with the judge before he rules on objections, the admissibility of evidence, and other legal matters.

The judge imposed a limited gag order prohibiting statements about his staff after Trump posted about the clerk on social media.

Donald Trump and his co-defendants have filed a motion seeking a mistrial on the grounds that the trial has been "tainted" by the appearance of bias on the part of Judge Arthur Engoron and his law.

"This appearance of bias threatens both Defendants' rights and the integrity of the judiciary as an institution," Trump's attorneys say in the filing. "As developed herein, in this case the evidence of apparent and actual bias is tangible and overwhelming."

"Specifically, the Court’s own conduct, coupled with the Principal Law Clerk, Allison Greenfield’s unprecedented role in the trial and extensive, public partisan activities, would cause even a casual observer to question the Court’s partiality," they write.

"Such evidence, coupled with an unprecedented departure from standard judicial procedure, has tainted these proceedings and a mistrial is warranted," the filing says.

Donald Trump's lawyers are scheduled to resume their direct examination of expert witness Jason Flemmons this morning, continuing a line of questioning yesterday that largely placed responsibility for Trump's financial statements on Trump's external accountants.

Flemmons, who was qualified as an expert on accounting, explicitly criticized the testimony of Donald Bender, Trump's accountant at Mazars USA who was the New York attorney general's first witness, disputing Bender's claim that he would have wanted to see any appraisals that the Trump Organization conducted.

Flemmons also testified that Trump's financial statements should have sent a "buyer beware" signal to lenders due to the "highly cautionary language" in their disclaimer, which allowed Trump to make claims that significantly departed from generally accepted accounting principles.

To the extent that the statements and the Trump Organization's representations about the statements were inaccurate, Flemmons placed responsibility on Bender and his colleagues at Mazars, rather than the Trump Organization.

Expert witness Jason Flemmons cast doubt on the testimony of the Trump Organization's former external accountant Donald Bender, who said he would have wanted to review any appraisals that the Trump Organization conducted.

"That's not something that is required by professional standards," said Flemmons, testifying for the defense. "His testimony was not professionally plausible."

That prompted a strong objection from state attorney Kevin Wallace.

"Is he trying to say the witness is lying?" Wallace said.

"Not to put too fine a point on it," Judge Engoron quipped.

Asked to confirm what he meant by "professional plausible," Flemmons said it would be "highly unusual" for Bender to request appraisals outside what was mentioned in the statement of financial condition.

"Accountants in the industry do not go seeking records for things that are not in the four corners of the statement of financial condition," Flemmons said.

Court was subsequently adjourned for the day, with Flemmons scheduled to continue his testimony tomorrow.

Trump Organization executive Patrick Birney testified that CFO Allen Weisselberg and controller Jeffrey McConney had the final say on Trump's financial documents when he worked under them.

"I was not the final decision maker," said Birney, who was an assistant vice president at the time.

Birney joined the Trump Organization in 2015, a few years after he graduated from the University of Michigan. He began helping with Trump's statement of financial condition in 2016 and eventually took over preparing the vital financial document, though he acknowledged in court that he initially lacked some basic knowledge about accounting and finance.

Asked if he ever had valued a property using a capitalization rate, he replied, "I don't think so."

Birney said he would often turn to McConney if he needed specific documents, and that he reviewed drafts of the statement with Weisselberg.

"He would review drafts with me that I would provide him," Birney said. He later added, "Allen Weisselberg had the authority to approve everything."
