Eric Trump denied knowing that he was cited as a source for Donald Trump's valuation of his Seven Springs estate in New York.

"People ask me questions all the time, but I never worked on the statement of financial condition," Eric Trump said when asked about two phone conversations cited by Trump Organization controller Jeffrey McConney to determine the value of the estate.

While Eric Trump said he had no reason to doubt that the conversations about the estate took place, he denied knowing they were used to value the property in Trump's financial statements.

"I don't believe I ever saw or worked on a statement of financial condition," Eric Trump said.

Eric Trump, the heir apparent to the Trump Organization, could face particularly high stakes on the stand.

Gaining power in his family's firm once his father became U.S. president, Eric Trump is responsible for "all aspects of management and operation of the Trump Organization," according to New York Attorney General Letitia James.

While his brother Donald Trump Jr. was sparsely mentioned by witnesses during the first five weeks of the trial, Eric Trump was described by witnesses as involved in the day-to-day operations of the company, as well as leading projects for multiple properties that were allegedly inflated in his father's statements of financial condition.

Unlike his brother Donald Trump Jr. -- who certified those statements between 2016 and 2021 -- Eric Trump is alleged to have signed "several guarantor compliance certificates" for his father, that relied on the financial statements.

"I've done a lot to jog my memory and I simply can't, because I don't think I've had any involvement in the statement of financial condition, to the best of my knowledge," Eric Trump said during the deposition he gave in the course of the AG's investigation.

As part of the penalty she is seeking, James has requested that the court bar Eric Trump -- as well as his brother and father -- from serving as an officer in any New York State corporation or business entity.

"The people call Eric Trump," state attorney Andrew Amer said as Donald Trump's second son took the stand.

"Is it fair to view the hierarchy of the Trump Organization as a pyramid with your father at the top?" Amer asked Eric Trump, an executive vice president with the firm.

"Yes," Eric Trump said. "I worked with many people but ultimately reported to my father."

Donald Trump Jr. has stepped down from the stand after testifying yesterday afternoon and this morning.

Trump Jr., who appeared comfortable and often smiled at the judge during most of his direct examination, began to invoke attorney-client privilege toward the end of his testimony, when he was asked about conversations within the Trump Organization after executives there learned of the New York attorney general's probe.

"Did you have anything to do with the statements of financial condition?" the judge intervened to ask Trump Jr. about the documents at the center of the AG's case.

"No, I did not, your honor," Trump Jr. said.

Defense lawyers declined to cross examine their own client.

Former President Donald Trump's plan to deliver part of his closing argument Thursday, as reported yesterday by ABC News, is now in doubt after he failed to meet a deadline to agree to limitations imposed by Judge Arthur Engoron.

According an email exchange between Engonon and defense counsel that was posted to the public docket Wednesday, Engoron said that Trump would have to follow the case's limited gag order, and that he would not be allowed to "impugn" the New York attorney general or her staff -- limitations that Trump attorney Chris Kise rejected, calling them "untenable."

"The limitations I am imposing, in my absolute discretion, are not subject to further debate. Take it or leave it," Engoron replied on Jan. 9, according to the email thread.

When Trump's lawyers missed the first deadline set by Engoron, the judge determined that Trump could not testify. Kise then responded that he did not see the deadline and requested that the closing arguments be postponed because of the death of Melania Trump's mother on Tuesday.

"I am sad to advise the Court that Mrs. Trump's mother passed away this evening. Because of the challenges presented by this deeply personal family matter, President Trump has asked that I request the Court postpone the date for closing argument," Kise wrote yesterday.

Engoron promptly denied the request and said the closings would continue as planned.

"On balance, going forward makes the most sense. Please tell Mr. Trump that I am sorry," Engoron wrote.

Kise informed Engoron that Trump still planned to attend the closings and speak.

"Despite the fact that his Mother-in Law, who he was very close to, passed away late last night, President Trump will be speaking tomorrow," Kise said in an email this morning.

When Engoron asked for assurance that Trump agreed to his rules, Kise pushed back, writing, "You are not allowing President Trump, who has been wrongfully demeaned and belittled by an out of control, politically motivated Attorney General, to speak about the things that must be spoken about."

"I won't debate this yet again. Take it or leave it. Now or never. You have until noon, seven minutes from now. I WILL NOT GRANT ANY FURTHER EXTENSIONS," Engoron replied at 11:54 a.m.

After Kise failed to respond, Engoron emailed him at 12:12 p.m. that he assumed Trump would not be speaking and that their email exchange would be posted to the court's public docket.

Responding to the development, Trump's legal spokesperson, Alina Habba, said in a statement to ABC News: "Is anyone surprised anymore?"
