Former President Donald Trump signaled he will be in court again Tuesday morning in a post on his social media platform.

"See you in Court Tuesday morning," Trump posted.

The former president then went on to attack New York Attorney General Letitia James. He claimed he had a "good day at trial" during Monday's proceedings.

Testifying about the preparation of the Trump Organization's statements of financial condition in 2011, former Mazars USA accountant Donald Bender said Trump executives largely provided the input data for statements, in addition to dictating the standards by which the work was completed.

"We would cut and paste that information into a new worksheet," Bender said about the approach taken by Mazar after receiving new data from co-defendant Jeffrey McConney of the Trump Organization.

When asked about the compliance with the Generally Accepted Accounting Principles -- which Bender testified are the standards for accounting in the United States -- Bender repeatedly placed responsibility in the lap of the Trump organization.

"That was the Trump Organization's responsibility," Bender testified about GAAP compliance.

Bender acknowledged that he rarely questioned the inputs from the Trump Organization, and when he did, he largely dealt with McConney and executives other than Trump and his adult sons.

Repeatedly asked by the state attorney if Mazars would have issued the statements if they had known the Trump Organization included material misrepresentations in their data, Bender reiterated that Mazars would not have issued the statements.

When Judge Engoron remarked at the end of the trial day that the state would still need to present further evidence to prove that the 2011 statement was within the statute of limitations, Trump seized the statement as a partial victory.

"The last five minutes was outstanding, because the judge actually conceded that the statute of limitations … is in effect," Trump told reporters as he was leaving court.

Engoron, however, did not completely rule out the 2011 evidence during trial, instead appearing to remind counsel that they need to show the 2011 statement represents an ongoing concern that falls within the statute of limitations.

Testimony is scheduled to resume on Tuesday at 10 a.m. ET.

Prosecutors have called their first witness to the stand: Donald Bender, a former accountant at Mazars USA, the firm that for years handled Trump's taxes.

Bender testified at length about his involvement in compiling Trump's statements of financial condition between 2011 and 2020, which he described as "balance [sheets] of Mr. Trump's assets and liabilities."

Bender said the standards and inputs for the statements were largely decided by Trump Organization executives.

"That was the Trump Organization's responsibility," Bender said about the accounting standard used in the statements.

As Bender answered the state's questions, Trump was seen taking notes at the defense table.

Bender described spending roughly half his time on Trump's business and personal financial matters toward the end of his career at Mazars.

The firm severed its business relationship with Trump last year after learning of the attorney general's findings during the AG's probe.

Former President Trump took swipes at the attorney general and the judge overseeing his case during a break, calling the trial a "disgrace," and saying that he will return over the course of proceedings.

"I'll be seeing a lot of you," he told reporters, "because this is a horrible thing that's happening to this country."

He again claimed the civil lawsuit brought by AG Letitia James -- as well as the litany of other cases he faces -- are politically motivated.

"If I weren't leading in all the polls, or if I weren't running, I wouldn't have any of these cases," Trump said.

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.
