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.

Donald Trump Jr. struggled to answer questions when pressed about why former Trump Organization CFO Allen Weisselberg departed the family's firm.

"Because some legal issues he got himself into," Trump Jr. said, declining to offer specifics about Weisselberg's guilty plea on tax evasion charges last year.

Previously giving lengthy answers to questions about his background and even smiling with the judge, Trump Jr. appeared tense on the witness stand as he answered questions about Weisselberg.

"The specific event was he was indicted," Trump Jr. said.

He added that when began working for the Trump Organization as an executive vice president in the 2010s, Weisselberg outranked him. Trump Jr. would seek Weisselberg's approval for certain business decisions such as refinancing loans.

"Who is above you in your role as an executive vice president in the Trump Organization?" state attorney Colleen Faherty asked.

"Obviously I would have reported to my father in that period of time … people like Allen Weisselberg would have still been senior to me," Trump Jr. said of that time period.

Trump Jr. said he gained more responsibility in 2016 when his father became president and he was named a trustee of his father's revocable trust. He said that he, Weisselberg and his brother Eric Trump became a kind of triumvirate running the Trump Organization.

"We stopped reporting to my father on decisions involving the business," Trump Jr. said.

That relationship broke down once Weisselberg got himself into "legal issues," Trump Jr. said. He testified that he could not recall the circumstances of Weisselberg's exit, including the multimillion-dollar severance deal that Weisselberg received, which Weisselberg faced questions about during his own testimony earlier this month.

"I have no knowledge of the specifics of how it happened. He is no longer working at the Trump Organization," Trump Jr. said of the former CFO.

"Sounds very exciting, but no," Donald Trump Jr. answered to a state attorney's question about whether he knows about accounting certifications, professional organizations, or accounting standards other than GAAP, which stands for "Generally Accepted Accounting Principles."

"I know nothing about GAAP," Trump Jr. said, adding, "I leave it to my CPAs."

"I'm a real estate broker," Trump Jr. said as he introduced himself on the witness stand. He testified that he began working in the family real estate business "right after 9/11," working on Trump Park Avenue and the former Sun Times building in Chicago.

State attorney Colleen Faherty tried to pressed him on his lack of accounting knowledge, prompting several objections from the defense.

Judge Engoron sustained the objections and admonished Faherty against asking negative questions.

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."
