"Would you like to call your first witness, defense?" Judge Arthur Engoron asked to begin court this morning.

"The defense calls Donald Trump Jr. to the stand," defense attorney Clifford Robert responded.

Like his last time on the witness stand when he was called by state attorneys, Trump Jr. appears comfortable on the stand, punctuating his testimony with lighthearted remarks.

Robert began his direct examination with some questions about Trump Jr. 's biography, starting with his graduation from the University of Pennsylvania.

"Was a bartender for about 18 months," Trump Jr. said about his first job out of college.

"Did you enjoy that?" Robert asked.

"I did," said Trump Jr., joking that he had a challenging conversation with his father when he began that job.

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.

Trump Organization executive Patrick Birney testified that CFO Allen Weisselberg and controller Jeffrey McConney had the final say on Trump's financial documents when he worked under them.

"I was not the final decision maker," said Birney, who was an assistant vice president at the time.

Birney joined the Trump Organization in 2015, a few years after he graduated from the University of Michigan. He began helping with Trump's statement of financial condition in 2016 and eventually took over preparing the vital financial document, though he acknowledged in court that he initially lacked some basic knowledge about accounting and finance.

Asked if he ever had valued a property using a capitalization rate, he replied, "I don't think so."

Birney said he would often turn to McConney if he needed specific documents, and that he reviewed drafts of the statement with Weisselberg.

"He would review drafts with me that I would provide him," Birney said. He later added, "Allen Weisselberg had the authority to approve everything."
