Donald Trump Jr. and his defense lawyers arrived at the New York State Supreme Courthouse this morning to be met with a small crowd of protestors chanting "crime family."

Trump Jr. did not make a statement before entering the courthouse, but offered a brief response to a question about his expected testimony.

Asked what he plans on saying today on the stand, he replied, "We'll see what I'm asked."

New York Attorney General Letitia James arrived at court shortly after Trump Jr. and took a seat in the courtroom with her staff.

Donald Trump Jr. took in some ultimate fighting ahead of his scheduled return to the witness stand this morning.

Trump Jr. attended a UFC doubleheader at Madison Square Garden on Saturday night with his father, in addition to Tucker Carlson, Kid Rock, and UFC president Dana White.

"I legitimately can't think of a better squad to roll with," Trump Jr. posted on social media.

Earlier that day while speaking at a campaign rally in New Hampshire, Donald Trump appeared to joke about appointing White to a position in a potential future administration.

"He's a guy I'd like to make my Defense Chief. I wouldn't call him my defense chief. I'd call him my 'Offense Chief.' He'd be my Offense Chief," Trump said.

As Trump's legal team prepares to begin presenting its case this morning, defense attorney Alina Habba says responsibility for the financial statements that the New York attorney general says are fraudulent lies with Trump's external accounting firm.

Previewing the defense's case during an appearance on Fox's Sunday Morning Futures with Maria Bartiromo, Habba also said the banks that loaned money to the Trump Organization were responsible for conducting their own due diligence regarding Trump's financial statements.

The state rested its case last week in the sixth week of the trial. The defense has said they expect their case to wrap up by Dec. 15.

Habba also suggested that Donald Trump plans to file a motion seeking a mistrial.

While Habba declined to comment on alleged misconduct by Judge Arthur Engoron's clerk -- which she is prohibited from doing due to the limited gag order handed down by the judge -- she said the issue would be addressed in their mistrial motion "very soon."

"I actually can't tell you why, because I am gagged. I can tell you that we will be filing papers to address all of those issues," Habba said.

However, Habba downplayed the chance the motion would be favorably decided Engoron.

"The problem we have is the judge is the one who is going to make those decisions, and he has proven himself to be quite motivated by the other side," Habba said.

In response to Rep. Elise Stefanik's letter of complaint against Judge Engoron that she filed Friday with the New York State Commission on Judicial Conduct, a spokesperson for New York State Office of Court Administration has issued a statement.

"Judge Engoron's actions and rulings in this matter are all part of the public record and speak for themselves," said Office of Court Administration communications director Al Baker. "It is inappropriate to comment further."

Taking the witness stand as an expert witness for the defense, accountant Jason Flemmons offered testimony in support of Donald Trump's approach to valuing his Mar-a-Lago property, which has been the subject of debate throughout the seven weeks of the trial.

In his summary judgment decision, Judge Engoron found that Trump overvalued the estate by at least 2,300% because the Palm Beach County Assessor appraised the property's market value between $18 and $27.6 million after Trump signed a deed that restricted its use to a social club, potentially limiting its resale value as a residence but ensuring a tax cut. Trump, in contrast, listed its value in his financial statement between $426 million and $612 million, and during his appearances in court and online he has repeatedly attacked Engoron's finding.

Flemmons argued that Trump's approach to valuing his assets gave him latitude to consider his property's future revenue streams. That approach, according to Flemmons, could result in "wildly different values" between the numbers listed on a personal financial statement and a tax assessed value.

"Tax assessed values are typically on the lower end of the spectrum," Flemmons said, while Engoron looked on attentively.

While he never mentioned Mar-a-Lago by name, Flemmons was asked by defense attorney Jesus Suarez about a hypothetical property assessed at $18 million but valued closer to $500 million using a comparable sales approach -- the same approach used to value Mar-a-Lago.

"It would not be unusual to have a value in the hundreds of million using projected cash receipts," Flemmons said.

Engoron then turned his chair toward Flemmons and began asking his own questions.

"I am trying to get to the order of magnitude we are talking about here," Engoron said. "What is the highest value you have ever seen legitimately placed on such a property?"

Flemmons could not provide a specific example to answer Engoron's question but reiterated that a massive discrepancy could be appropriate.
