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.

Donald Trump acknowledged during direct examination that he overvalued at least two properties in his statements of financial condition, though he broadly represented that the statements underestimated his total net worth.

"Did you ever think that the values were off in your statement of financial condition?" state attorney Kevin Wallace asked about the document at the center of the case, which the New York attorney general has alleged contained fraudulent valuations.

"Yes, on occasion. Both high and low," Trump said, appearing to surprise Wallace, who paused to allow Trump to continue his answer.

Compared to his sons, who largely testified that they deferred to accountants and lawyers, Trump portrayed himself as an experienced businessman who "was certainly more expert than anybody else" when it came to the value of his own properties.

Asked about properties like 40 Wall Street and a retail space near Trump Tower, the former president confidently used real estate shorthand to explain why he thought certain properties were undervalued. He also repeated that his brand value -- which was not included in his financial statement -- is worth billions.

"The most valuable asset was the brand value," Trump said. "I became president because of my brand."

However, Trump acknowledged that two properties -- his triplex apartment in Trump Tower and his Seven Springs estate in New York's Westchester County -- were overvalued and had to be adjusted in his financial statement.

"I thought the apartment was overvalued when I looked at it," Trump said, appearing to refer to a $200 million correction applied to his statement after Forbes magazine reported that he falsely stated the apartment was three times its actual size.

Asked about the change in the statement, Trump acknowledged the square footage mistake, which he blamed on a broker, while also claiming that the number was "not far off" from reality when you consider the square footage of Trump Tower's roof.

"It's a mistake … [but] there's a disclaimer clause so you don't have to get sued by the attorney general of New York," Trump said.

Trump made a similar admission about the $291 million valuation of Seven Springs.

"I thought it was too high and we lowered it," Trump said, though he could not provide specifics about the changed valuation.
