As Donald Trump Jr. prepares to return to the witness stand this morning, New York Attorney General Letitia James says the Trump Organization executive VP has been been with the Trump Organization for a long time for someone who appears to have so little understanding of the business.

In a video posted to social media last night following Trump Jr.'s first day of testimony, James said the eldest son of former President Trump "claimed to have very little understanding of the accounting and legal mechanics of the family business -- but we know he has been involved in running the Trump Organization for a long time."

Trump Jr. testified yesterday that he relied on the expertise of others when he signed his father's statements of financial condition, distancing himself from the documents at the heart of the attorney general's case.

While he acknowledged that he had some of the "the most intimate knowledge" about some of the deals described in the statements, Trump Jr. reiterated that he did not have a role in putting the documents together.

"The accountants worked on it. That's what we pay them to do," Trump Jr. said.

Trump Jr. will return to the witness stand this morning, with his bother Eric Trump on deck to testify later today.

Before stepping down from the witness stand at the end of the afternoon, Donald Trump Jr. was asked repeatedly about his involvement in the Trump Organization's statements of financial condition -- the allegedly fraudulent documents that underpin the attorney general's case.

Trump Jr., who signed and certified the accuracy of the statements while his father was president between 2016 and 2021, said that he was not involved in preparing the filings.

"I wasn't involved in the compilation of this statement of financial condition," Trump Jr. said, placing the responsibility on his accountants.

"Did you work on the statement of financial condition for June 30, 2017?" state attorney Colleen Faherty asked.

"I did not. The accountants worked on it. That's what we paid them to do," Trump Jr. said.

Throughout the afternoon, the tone of the proceedings alternated rapidly between lighthearted and heated, varying from playful interactions between Trump Jr. and Judge Engoron, to bitter spats between some of the lawyers.

"I know you don't like it when good evidence comes in," Faherty told the defense lawyers during one particularly heated exchange.

"There's no reason to raise your voice," Donald Trump Jr.'s lawyer, Clifford Robert, responded.

Trump Jr. is scheduled to return to the stand tomorrow morning.

Donald Trump Jr. has stepped down from the witness stand.

He is due to return to the courtroom tomorrow morning to resume his direct examination.

Court is now adjourned for the day.

Donald Trump Jr. and state attorney Colleen Faherty got into a rhythm of quick questions and answers during the first hour of direct examination.

"I moved to Florida, but kept the New York pace," Trump Jr. joked at one point when asked by the judge to speak slower.

So far the state attorney has focused most of her questions on Trump Jr.'s broader roles and responsibilities at his family's firm, rather than any specific allegations in the attorney general's complaint.

"I don't see where we are going at all with this," Trump attorney Chris Kise said at one point regarding the questioning.

"Move it along as fast as you can," Judge Engoron told Faherty.

When the Trump Organization valued its Seven Springs compound in New York's Westchester County at $261 million, the company included seven mansions, estimated to be worth $23 million each, that had not been built, longtime Trump Organization controller Jeff McConney testified.

In contrast, an appraiser had said Seven Springs was worth $56 million, excluding development rights for the property, which hadn't been awarded.

McConney testified that he did not factor into the valuation when, or whether, the homes would be built.

"You have treated, for the purposes of this valuation, a profit of $23 million per home as if it were realized immediately?" asked Andrew Amer with the New York attorney general's office.

"Correct," McConney said.

Amer said that Trump Organization VP Eric Trump, in a call with McConney the following year, instructed McConney to continue to value the seven mansions the same as he did in 2013.

McConney is testifying as a hostile witness since he is also a named defendant in the case. It gives Amer wider latitude in his examination, though defense attorneys have made several objections about leading questions.

The proceedings were briefly interrupted by the blaring of a horn that was audible in the courtroom, prompting Amer to interrupt his questioning and remark, "Someone is having a celebration."

Judge Engoron, who has displayed a dry wit throughout the trial, responded, "Maybe they're celebrating us."
