Ivanka Trump stepped down from the witness stand following a day of testimony that saw the proceedings grow more heated as the afternoon wore on.

At one point toward the end of her cross-examination, Ivanka Trump delivered a lengthy response about working with Democratic lawmakers to execute the redevelopment of the Old Post Office in Washington, D.C., which became a Trump-owned hotel in 2016.

When defense attorney Jesus Suarez sought clarification that those lawmakers were Democrats, attorneys sitting at the state's counsel table appeared to laugh -- infuriating Suarez.

"I have to sit here and ask questions and listen to them laugh?" Suarez shouted, pointing at members of the attorney general's office and calling their conduct "insulting."

"They're sitting there laughing ... it's not funny," Suarez said.

Judge Engoron sought to quell tempers, framing the reaction as an expression of amusement regarding the repetition of Suarez's questioning.

"I think they are laughing … three, four, five times that these were congressional representatives," Engoron said. "Maybe they found the question funny."

After a relatively calm day, tensions flared between Judge Engonon and Trump lawyer Chris Kise, after Kise accused the judge of applying a "double standard" to the defense team.

Defense attorney Jesus Suarez attempted to question Ivanka Trump about a document from the General Services Administration, prompting an objection from state attorney Louis Solomon, who argued that Suarez lacked the foundation to ask about the document.

"I've objected hundreds of times now," an exasperated Kise said, arguing that the state attorneys used documents with less foundation provided.

"I continually object to your constant insinuation that I have some sort of double standard. It's just not true," Engoron replied forcefully.

Ivanka Trump, sitting feet away from Engoron, appeared to watch the exchange in disbelief.

"I wish it were different. I respect your honor's position. I just see these ruling ... frequently going in a different direction," Kise said.

"Their objections have been of greater validity than yours," Engoron shot back.

Following a sometimes-tense direct examination by state attorney Louis Solomon, Ivanka Trump is speaking more comfortably, showing more emotion, and offering more lengthy answers to questions during cross examination.

Asked about why the Trump Organization worked with Deutsche Bank to secure financing for its purchase of the Doral golf club in Miami, she spoke wistfully about the property.

"My father had a deep and nostalgic love for that particular property," she testified.

"He told me he took my mother there," she said with a smile, recalling her father bringing her there when she was a child.

"They were really impressed by what we had done over the course of several years in terms of upgrading and refurbishing the property," Ivanka Trump said.

Deutsche Bank sought to promote its ties to the Trump Organization in marketing materials a decade ago, according to emails shown in court during Ivanka Trump's ongoing cross-examination.

Trump attorney Jesus Suarez showed the emails to demonstrate a key pillar of their defense: that the state's allegations were victimless, and in fact, rather than getting bilked in loan agreements, bankers appreciated -- and even competed for -- the Trump Organization's business.

"I was constantly told by Rosemary and her team how much they appreciated our relationship and ... seeking to grow it," Ivanka Trump testified regarding Deutsche Bank executive Rosemary Vrablic.

Deutsche Bank asked Ivanka Trump to appear in promotional videos for their firm, the emails suggested.

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."
