Defense attorney Clifford Robert continued to hammer at real estate appraiser Doug Larson during cross-examination.

Larson -- who met with attorneys from the New York attorney general's office on Monday in advance of his testimony -- was asked if he was shown either of the two emails that this morning prompted him to recall having phone calls with Trump Organization controller Jeffrey McConney, after testifying yesterday that he did not.

"During your prep session Monday, the attorney general didn't show you these two documents?" Robert said while waving printed copies of the two emails in the air, to which Larson replied no.

State attorney Mark Ladov, on redirect examination, read a transcript from an interview with Larson from three years ago, in which Larson was shown the emails and offered a response that was consistent with yesterday's testimony.

"This is beyond absurd," Trump attorney Chris Kise said, objecting to Ladov's approach.

Exiting the courtroom during a break, Trump seized on the Larson's testimony to support his claims that the case should be dismissed.

"The government just got caught in a big, fat lie," Trump said.

Trump, who has been sitting at the counsel table with his attorneys Chris Kise and Alina Habba, had a noticeable response when real estate appraiser Doug Larson denied having conversations with Trump Organization controller Jeffrey McConney about the value of Trump's 40 Wall Street property in 2013.

The former president made an inaudible comment, tapped on the table, and conferred with his lawyers.

That prompted state attorney Kevin Wallace to ask Judge Engoron to tell Trump to refrain from making comments.

"Can the defendant please stop commenting during the witness' testimony?" Wallace said. "I believe exhortations are audible on this side of the courtroom as well."

Engoron declined to specifically tell Trump to refrain from commenting, instead saying, "I will ask everyone to be quiet when the witness is testifying."

With Donald Trump sitting just feet away, lawyers for Trump and New York Attorney General Letitia James engaged in a heated argument about whether an expert real estate appraiser committed perjury during his testimony yesterday.

"You lied yesterday, didn't you?" defense lawyer Lazaro Fields asked former Cushman & Wakefield real estate executive Doug Larson -- a line of questioning that prompted Larson to be excused from the courtroom while the attorneys sparred.

"This witness has rights and a lawyer in the room," Trump lawyer Chris Kise said, while lawyers for the state shouted "absurd" and "witness intimidation" from their chairs.

The squabble centered on Larson's testimony about whether he assisted the Trump Organization in determining capitalization rates to value their properties.

"Did you work with Mr. McConney in 2013 to determine the cap rate that he used to value his property?" state attorney Mark Ladov asked Larson yesterday, referring to Trump Organization controller Jeffrey McConney.

"No, I did not," Larson testified yesterday.

Fields attempted to contradict Larson's answer this morning by showing emails between McConney and Larson that suggested the two occasionally spoke about market conditions.

"Jeff McConney would call me, periodically, not frequently, to talk about sales and market conditions," Larson conceded.

But Larson denied having conversations with McConney about the value of Trump's 40 Wall Street property in 2013.

After a brief interruption, Fields presented a 2014 email where McConney asked Larson, "I hate to be a pest, but the accountants are coming in tomorrow to go over my valuations. Any chance you can answer my question below?"

Asked about that email, Larson acknowledged that McConney was using his information to support Trump Organization valuations in 2013.

It was at this point that Fields directly asked if Larson had lied yesterday, prompting the witness to be excused briefly.

"He perjured himself yesterday, in my opinion," Kise told the court.

"This is a performance … not a legal issue," Wallace countered.

"He was accused of perjury on the stand," Engoron noted before bringing Larson back into the courtroom.

While Larson still denied that he "worked with" McConney on the valuations, he ultimately conceded that he knew the information he provided was used to value Trump properties at the time -- seemingly contradicting his testimony yesterday.

"You knew in 2013 that Mr. McConney was using the information you sent him, mainly the capitalization rates, to value the Trump properties?" Fields said.

"I did," Larson said.

Former President Trump is back in court for the second day in a row.

New York Attorney General Letitia James is also attending the proceedings this morning.

Trump was met with a swarm of cameras on his way into the court, though the courtroom itself is half empty, largely filled with reporters and security officers.

Like yesterday, Trump is sitting at the counsel table between his attorneys Chris Kise and Alina Habba.

Cushman & Wakefield executive David McArdle, who was hired to appraise the value of 71 undeveloped residential units at the Trump National Golf Club in Westchester County, New York, testified that he also conducted multiple appraisals for conservation easements at the property in 2014 and 2015.

Signing a conservation easement would allow the Trump Organization to give up their development rights and treat the difference in property value as a charitable donation, according to the New York attorney general.

By giving up the right to develop the 71 residential units, McArdle found that the donation was worth $43 million, according to an April 2014 appraisal. A later appraisal McArdle conducted in 2015 landed on a similar valuation of $45.2 million.

But Trump's financial statements from those years appear to ignore the appraisals, valuing the land from the undeveloped units at $101 million, according to documents entered into evidence.

"Based on the supporting data, the only source for the increase in the number of units and profit per unit were telephone conversations with Eric Trump," the New York attorney general alleged in her complaint.

McArdle also testified that he was consulted to appraise Seven Springs, a New York estate Trump purchased for $7.5 million in 1995.

To value the property, which could be subdivided into 24 to 26 residential lots, McArdle testified that he toured the site, consulted a local expert, and spoke with Eric Trump on multiple occasions.

"He had a very high opinion of the property, which didn't surprise me," McArdle said.

His appraisal ultimately determined the total value for the lots in 2014 was $30-$50 million, McArdle said.

But the New York attorney general alleges that appraisal was ignored in Trump's 2014 financial statement, in favor of a "false and misleading" value of $161 million for a portion of the undeveloped lots.
