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.

The New York attorney general's civil fraud complaint against former President Trump lacks merit, a defense expert in accounting testified.

"My main finding is that there is no evidence whatsoever for any accounting fraud," New York University professor Eli Bartov said. "My analysis shows the statements of financial condition for all the years were not materially misstated."

Bartov's testimony bolstered the defense's contention that non-audited financial statements, like Trump's, are unreliable and represent only a first step in analysis.

"You cannot use the raw numbers in the statements as the basis for making decisions," Bartov said. "If you do that, you are likely to reach the wrong decision."

Judge Engoron asked Bartov whether the attorney general's complaint had no merit.

"This is absolutely my opinion," Bartov replied.

"And why is that?" defense attorney Jesus Suarez jumped in to ask.

"There is not a single reference to a specific provision of GAAP that was violated," Bartov said, referring to the generally accepted accounting principles." "If you allege there was an accounting violation, they have to tell us what provision was violated."

State attorneys objected to the relevance of Bartov's opinion, but Judge Engoron denied the objection.
