Ivanka Trump's husband Jared Kushner, who like Ivanka Trump served as a senior adviser in the Trump White House, would frequently weigh in on her family's real estate negotiations in the years before Donald Trump became president, Ivanka Trump testified.

State attorneys shared emails Ivanka Trump had sent her husband during negotiations with bankers over loan interest rates. Asked by state attorney Louis Solomon why she would share those records with Kushner, Trump responded, "It is not uncommon that I would ask my husband's perspective on something I was working on."

"My husband also was in real estate, and would have perspective for me," she said of Kushner, who, like Ivanka Trump, is not a defendant in the case. "So periodically we would discuss what we were working on."

Attorneys for Trump challenged the admissibility of emails belonging to Kushner, citing spousal privilege.

Justice Engoron overruled those objections because they communicated over work emails.

"If you use a work email that is subject to being seen by other people, you waive confidentiality," Engoron said.

Donald Trump's lawyers are scheduled to begin presenting the defense's case on Monday following the conclusion of the presentation of the New York attorney general's case -- but New York AG Letitia James is arguing that four of the defense's expert witnesses are no longer relevant.

In a filing made today, James argues that Judge Engoron's partial summary judgment decision and subsequent changes to the state's case have made make the testimony from the four experts irrelevant.

State lawyers plan to make an oral motion to preclude the expert testimony tomorrow, according to their filing.

State attorney Louis Solomon grew visibly frustrated with Ivanka Trump's limited recollections during an exchange about Donald Trump's Old Post Office building in Washington, D.C.

Solomon attempted to confront Ivanka Trump with a document that showed that the General Services Administration -- which ran the selection process for the renovation of the building -- raised concerns about Donald Trump's financial statements in 2011. New York Attorney General Letitia James, who says the statements contained fraudulent valuations, alleges that both Donald Trump and Ivanka Trump addressed those concerns during an in-person meeting with GSA officials.

"It was a general presentation. I don't recall with specificity any discussion of financial statements," Ivanka Trump said, prompting Solomon to throw his hands in the air.

"When I ask a question, she doesn't remember," an exasperated Solomon said. "The witness does have a recollection, your honor!"

"Would you like to clarify the situation?" Judge Engoron directly asked Ivanka Trump, who repeated the same description of the meeting.

"I recall one in-person meeting" about the "big picture" of the project, Ivanka Trump testified. She said recalled no discussion of "financial statements or anything granular like that."

Donald Trump's lawyers, meanwhile, have continued to object to Solomon asking questions about conduct from over a decade ago, which they say is akin to ancient history for a fast-moving real estate company.

"The GSA decision was made years before the statute of limitations," Donald Trump's lawyer Chris Kise argued, though Engoron overruled the objection.

Donald Trump is not in court today, but his lawyer is beginning to sound like the former president, according to a quip from Judge Arthur Engoron.

Describing the Trump Organization's renovation of the Old Post Office building in Washington, D.C., Trump's lawyer Chris Kise argued that the building was transformed from a "hulking relic" into a "world-class facility."

"You are starting to sound like your client," Engoron said, prompting some laughs from the gallery.

Deutsche Bank was a serious company in business with Donald Trump to make money, defense attorney Jesus Suarez said during his cross examination of former Deutsche Bank executive Nicholas Haigh.

At the height of its relationship with the Trump Organization the company loaned Trump over $378 million, and failed to commission independent appraisals of Trump's properties, Haigh acknowledged. While the bank listed lower estimates for the value of Trump's assets year after year, it continued to do business with Trump and his company.

"We ... the bank hadn't done all the due diligence one would do in the sense of the opinion of value you see in an appraisal," Haigh said, at one point agreeing with the defense's characterization that the bank's internal value services group conducted "sanity checks'' on the numbers.

The direct examination of Haigh by state attorney Kevin Wallace also left a central question about Deutsche Bank's activity unanswered.

In a letter to the court and in previous arguments, lawyers for the attorney general suggested that Haigh might have turned away Trump's business if he had known that Trump's assets were inflated in value.

"As this Court noted during summary judgment arguments, Mr. Haigh testified during OAG's investigation that he may not have authorized lending to the borrower if he had at that time been aware of the inflated asset values contained in Mr. Trump's SFCs [statements of financial condition]," a lawyer for the attorney general wrote to the court in a letter last week.

Wallace never directly posed the hypothetical to Haigh during his direct examination, leaving the question unresolved.

Court subsequently adjourned for the day, with Suarez telling the court he plans to continue his cross examination of Haigh through Thursday afternoon.
