Former President Trump attacked Judge Arthur Engoron and New York Attorney General Letitia James on social media ahead of today's expected testimony from his son Donald Trump Jr.

"Leave my children alone, Engoron. You are a disgrace to the legal profession!" Trump wrote overnight on his Truth Social platform.

Donald Trump Jr. is expected to begin his testimony in the afternoon today.

If that testimony concludes today, his brother Eric Trump could also begin his testimony.

Both of them are executive vice presidents in the Trump Organization.

Day 20 of the trial wrapped up with testimony from former Trump Organization vice president David Orowitz, who testified about what he said was Ivanka Trump's significant involvement in loan negotiations related to Trump's Doral Golf Club in Miami and the Trump International Hotel in Chicago over a decade ago.

Ivanka Trump, who at the time was a vice president in the Trump Organization, was dismissed from the AG's lawsuit in June because she was no longer with the firm by 2016 -- though she is still scheduled to testify next week as the final witness for the state's case.

State attorneys had initially planned to complete the testimony of Orowitz, as well as that of expert witness Michiel McCarty, by the end of today -- but Orovitz's lengthy testimony kept that from happening.

As a result, their remaining testimony will either delay tomorrow's much-anticipated testimony from Donald Trump Jr. -- or it will be pushed to a different day.

After claiming a net worth of $8 billion, Donald Trump declined to share his financial statements with bankers related to his $1 billion bid to purchase the Buffalo Bills football team in 2014, according to documents presented at trial and testimony from Morgan Stanley executive K. Don Cornwell.

Of the 86 parties contacted to potentially bid on the Bills, Trump was one of six parties to make a final bid, according to a Morgan Stanley document shown at trial.

However, when Morgan Stanley attempted a close review of Trump's bid, Trump declined to provide his financial statements.

"We feel it is premature to sign the consent release forms until such time as we know that Mr. Trump is the final bidder," then-Trump attorney Michael Cohen said in a 2014 email shown at trial.

During a management presentation with Bills' leadership, Trump instead handed out a Forbes magazine list to support his bid, according to Cornwell.

"He gave us handouts of the Forbes list of the top-paid entertainers," Cornwell said.

Trump eventually lost his bid to purchase the football team to billionaire Terry Pegula, who outbid Trump by $400 million.

During cross-examination, Cornwell acknowledged that a lawsuit Trump previously brought against the NFL, as well as his affiliation with casinos, also limited the likelihood of his success.

"You thought that President Trump had little chance of being approved by the NFL?" defense attorney Ivan Feris asked.

"Yes," Cornwell replied.

Trump's lawyers have argued that his bid to purchase the Bills -- which has featured prominently in the testimony of other witnesses -- is irrelevant to the conduct alleged in the attorney general's lawsuit.

"It is the defense position that none of this relates to a cause of action in this case," Feris said.

Attorneys involved in the case were greeted outside the courthouse this morning by nearly a dozen demonstrators wearing Halloween masks and carrying signs that read "Trick or Treason" and "Trump is a Horror Show."

"We came out because it's Halloween, and our theme is 'Trick or Treason,'" said organizer Jamie Baur of the group Rise and Resist. "We come out on different days, both to challenge [Trump's] lawyers and make sure they know that we hold them accountable for trying to defend the indefensible."

The group has demonstrated outside Trump's civil trial half a dozen times, in addition to holding weekly protests outside Fox News, according to Baur.

"They basically defrauded our state of lots and lots of money and [I am] hoping to see the judge get justice for their state taxpayers and residents," demonstrator Rick Weisfeld said.

Doug Larson's name appears across five years of Donald Trump's financial documents, according to records entered into evidence.

A longtime professional appraiser with the real estate firm Cushman & Wakefield, Larson was cited in Trump Organization documents as an expert at valuing properties like 40 Wall Street, Trump Tower, and an adjoining retail space called "Niketown." Spreadsheets entered as evidence explicitly reference multiple phone calls with Larson between 2013 and 2017.

When asked about these phone calls in court, Larson testified that no such conversations occurred.

"Is it fair to say that Mr. Trump valued Trump Tower at $526 million in conjunction with you?" state attorney Mark Ladov asked Larson.

"No, that is incorrect," Larson said.

"Were you aware that Mr. McConney was citing you as a valuation source in his work papers?" Ladov asked.

"No, I was not," replied Larson, who said he did not assist Trump Organization executives in valuing Trump Tower, Niketown, or 40 Wall Street, despite Trump's paperwork referencing him as a source.

Evidence presented by the state instead suggested that the valuations were determined using cherry-picked metrics from a generic email Larson sent clients.

"It's a way to get your name out to clients for potential work," Larson said about one such "email blast" that was used in a Trump Tower valuation.

Larson added that the valuations Trump Organization executives determined based on "consultation" with him used flawed methodologies, such as using capitalization rates related to office buildings to appraise the retail Niketown building.

"It doesn't make sense," Larson said about Niketown's $287 million valuation.

"It's inappropriate and inaccurate," Larson said about the Trump Organization relying on his name to support their valuations. "I should have been told, and appraisals should have been ordered."
