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.

Lawyers for the New York attorney general, in a late-day court filing, said they support the court-ordered pause on canceling Trump's business certificates -- but warn that a stay of Trump's civil fraud trial would cause a "cascade of delays."

The filing comes more than three weeks after an appeals court, at Trump's request, paused the enforcement of the cancelation of Trump's business certificates that Judge Arthur Engoron had ordered in his summary judgment.

In today's filing, New York Attorney General Letitia James wrote she was "willing to agree to stay enforcement … pending the end of trial and entry of final judgment."

On the other parts of Trump's appeal -- including the request to delay the trial and arguments against Engoron's summary judgment ruling that Trump committed fraud -- James vehemently argued in favor of letting the trial run its course.

"Abruptly halting trial would thus sow chaos and result in an inordinate waste of both public resources and the time and resources of witnesses," James wrote, alleging that Trump is playing courts against one another to create delays.

"Moreover, any delay here would threaten a cascade of delays not only in this case but also in other pending criminal and civil cases against defendant Donald J. Trump," the filing said.

Trump's legal team has until Nov. 9 to submit their reply.
