In a moment of levity during a break between witnesses, Judge Arthur Engoron noted that Trump attorney Chris Kise has not yet led the questioning of any witnesses.

"How come you don't get the pleasure of questioning people?" Engoron asked.

"There's still time left," Kise responded, saying that he prefers to coach his team from the sideline like famed New England Patriots coach Bill Belichick or Jimbo Fisher.

Fisher received a record buyout after being fired as coach of Texas A&M this week.

"I'd like to be fired from my job and collecting $77 million," Kise quipped.

"I'll see if I can arrange that," Engoron joked.

Steven Collins, an expert in contract procurement, testified that the federal government's General Services Administration -- which reviewed Donald Trump's proposal to renovate the Old Post Office in Washington, D.C. -- identified issues in Donald Trump's statement of financial condition.

"Financial statements provided by Mr. Trump was qualified by his accountants as not complying with GAAP" or generally accepted accounting principles, a GSA document entered into evidence said about a "notable weakness" of Trump's proposal.

However, said Collins, Trump's financial capability as reflected in the statements comprised no more than 15% of the evaluation factors considered by the GSA, which more heavily weighed Trump's site plan and financial offer in ultimately deciding to award Trump the contract.

Collins testified for roughly an hour for the defense and faced no questions during cross-examination.

State attorney Kevin Wallace, in his redirect examination of the defense's expert witness Jason Flemmons, asked the accounting expert a single question.

"When you were at the Securities and Exchange Commission, did you ever encounter issuers facing allegations of fraud [try] to throw their accountants under the bus?" Wallace asked, in an apparent jab at the defense's contention that the responsibility for Donald Trump's financial statements lies with his accountants.

Trump's lawyers quickly objected to the question. Judge Engoron, visibly smirking, sustained the objection.

Earlier, when asked by Judge Engoron about his compensation for serving as an expert witness, Flemmons said he was unable to estimate the total amount but that his hourly rate was $925 per hour. Michiel McCarty, who testified as an expert witness for the state, testified earlier this month that he charged a similar rate.

The defense's accounting expert, Jason Flemmons, testified that the process of determining the estimated value of a property could result in a range of values "no one of which is the right or wrong answer."

The assertion from Flemmons supports the defense's long-standing argument that performing valuations such as the ones listed on Donald Trump's statements of financial condition is more akin to an art than a science.

"Estimated current value is not an exact science. There is not one single correct value that comes of this exercise," Flemmons said.

Flemmons testified that insofar as Trump used an approved method to determine value, and disclosed that method, the value would be appropriate.

"You are communicating that to the user and allowing that user to be in a position to agree or disagree," Flemmons said.

State attorney Kevin Wallace has concluded his cross-examination of Flemmons, allowing defense lawyer Jesus Suarez to begin his redirect examination of the accounting expert.

Donald Trump's lawyers abruptly stopped the testimony of their first expert witness -- who was expected to testify for a full day or two -- after Judge Engoron limited the topic areas of his testimony.

Steven Witkoff, a real estate investor and longtime friend of Trump's, was brought into court by the defense team to testify that Trump's Doral golf club was undervalued in Trump's financial statements.

But Judge Engoron sustained an objection from the state barring any testimony about the valuation of Doral, significantly limiting Witkoff's testimony and appearing to hamper the defense strategy proposed by Trump's attorney Chris Kise.

Kise argued that the inaccuracies in Trump's statement of financial condition can cut both ways: Even if some properties were overvalued, other properties like Doral were significantly undervalued and balanced out the statement, according to Kise.

"It is highly, extraordinarily relevant if there are assets that are undervalued substantially on those same statements," Kise said. "They can't look at this one-sided."

State attorney Andrew Amer fiercely rebutted that argument, telling Engoron he should not take the defense's position that the inconsistencies "come out in the wash."

That argument appeared to convince Engoron, who said that overvaluations would not "insulate" a false valuation. He promised to sustain any objection that related to the value of Doral -- an approach Kise described as "lunacy."

"The reader of the financial statement has the right to know whether each particular number was accurate," Engoron said. "They are looking for accuracy."
