The competing obligations between the costs of Donald Trump's 2016 presidential campaign and his business obligations created a "cash crunch" at the Trump Organization that motivated the former president to commit fraud, state attorney Kevin Wallace argued during his summation.

Wallace's theory about the motivation for the alleged fraud, which he articulated for the first time, attempted to explain Trump's motive for the alleged conduct as well as justify levying a fine against Trump in order to regulate the marketplace.

According to Wallace, the hundreds of millions of dollars saved by the Trump Organization through fraud allowed the company to "stay afloat" during a major "cash crunch" during the 2010s.

During the first half of the decade, the Trump Organization spent roughly $775 million to renovate properties including its Doral and Turnberry golf courses, as well as the Old Post Office building in Washington, D.C., Wallace said. The idea that the company could have funded these expenses with cash alone was a "fantasy," according to Wallace.

"By the time you get to 2017, Mr. Trump was becoming president, and the company was getting low on cash," Wallace said. Faced with the chance of a negative cash flow, the company opted to embrace fraud, according to Wallace.

"They didn't have to choose between their priorities," Wallace said about the company's business expenses and Trump's presidential campaign.

Trump attorney Chris Kise objected to the argument, suggesting the theory was nothing more than conjecture -- which prompted a heated exchange with Wallace.

"Chris. Stop. We didn't interrupt the defendants' presentation at all," Wallace shouted while facing Kise.

"I think I agree with Mr. Kise," Judge Engoron responded, but he allowed the presentation to continue.

"We're back to hearing the same arguments," Kevin Wallace, an attorney with the New York state AG's office, began his closing statement following closing arguments from Trump's defense team.

"Donald Trump is rich, banks like rich people," Wallace said. "What we have not heard from defendants is any new facts."

Wallace said the defense failed to assert that any of the alleged fraud was a mistake, other than the overvaluation of the Trump Tower penthouse, and that the defense did not argue the numbers Trump used on his statements of financial condition were accurate.

"If you look at it across time, it becomes clear that fraud was central to the operation of the Trump Organization's business," Wallace said.

Wallace took aim at the testimony of defense expert witnesses, calling them a "murderer's row of experts" who Trump collectively paid at least $2.5 million.

"None of the experts actually presented evidence that is helpful to the court as a fact-finder," Wallace claimed.

Defense attorney Chris Kise stood up to interject, calling Wallace's murderer's row reference "outrageous." Wallace joked he was referring to the 1927 Yankees.

Moments after delivering his closing statement, Donald Trump exited the courtroom to criticize the trial as politically motivated.

"This is a political witch hunt the likes of which nobody's ever seen before. They owe me damages for what they've done," Trump said, repeating his claim that the case against him would scare businesses away from New York.

Nevertheless, the former president appeared pleased with his defense.

"It's been a pretty successful trial," said. "I don't know that we're going get a fair ruling. But everybody knows what I just said -- this is a sham and it's a shame," Trump said.

With the defense team's closings concluded, the state's closing is scheduled to begin following a break.

Judge Engoron mostly kept his head down for the duration of Donald Trump's closing summation, which Trump delivered from his seat at the defense counsel table.

"This is not how this should have been done," Engoron said seconds before Trump launched into his statement, which contained several accusations that Engonron had tried to prohibit Trump from making.

Calling the state attorneys "disgraceful" and the statute used against him "vicious," Trump repeated many of his lawyer's claims before arguing that he is the only victim of fraud in the case.

Trump also criticized Engoron himself, claiming that the judge would not listen to him.

"You can't listen for one minute," Trump said.

"Mr. Kise please control your client," Engoron said while attempting to reign in Trump. But Trump continued.

"I did nothing wrong. They should pay me for what we had to go through," Trump said. "She sued me to try to get publicity," he said of New York Attorney General Letitia James.

Engoron then held up his phone screen to signal to Trump that he had run out of time for his remarks, then the judge called for a break.

Judge Engoron has denied a motion from the New York attorney general to preclude four expert witnesses from testifying for the defense when the defense presents it case starting on Monday.

The state had sought to preclude the four experts' testimony on the grounds that, following the testimony of the state's witnesses, the four defense witnesses were no longer relevant to the case.

"You've won the battle. We'll see if you win the war," Engoron told defense attorney Chris Kise -- though he warned Kise that he would cut off the witnesses if they try to debate facts already established in the case.

In making his ruling, Engoron reiterated his finding from his earlier summary judgment order that Donald Trump made at least ten internally contradictory claims in his statements of financial condition.

"You can't have a correct statement with these kinds of errors," Engoron said.

Kise told the court that Donald Trump Jr. will be the first witness to testify in the defense's case on Monday.

"Oh, I know him," Engoron deadpanned after the announcement.

It will mark Trump Jr.'s return to the witness box after the state put him on the stand last week.
