Donald Trump still hopes to present a portion of the closing argument at his civil fraud trial Thursday, the former president said on social media.

Trump's statement comes after Judge Arthur Engoron threw his plan into doubt earlier Wednesday when the judge shared an email exchange in which Trump's lawyers declined to agree with the rules Engoron set for Trump's closing.

Characterizing Engoron's move as "mean & nasty," Trump said in his social media post that he still "would like to personally do the closing argument."

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?"

Former President Trump intends to personally deliver part of the defense's closing argument at the conclusion of his civil fraud trial in New York on Thursday, sources familiar with the former president's strategy tell ABC News.

The defendants in the case -- Trump, his two eldest sons and two former Trump Organization executives -- are represented by three primary attorneys, Christopher Kise, Clifford Robert and Alina Habba. But sources say Trump himself is determined to deliver a portion of the closing statement.

The sources cautioned that plans for the defense's closing argument remain fluid.

The Manhattan courtroom where the trial has been held during its first 11 weeks is currently in use for another high-profile trial involving the New York attorney general's case against the National Rifle Association, and the judge in that case told jurors that trial would temporarily move to a different courtroom this week to accommodate Trump's civil trial.

New York Attorney General Letitia James, in a written brief filed a week before the trial's closing arguments, asked the judge in the case to fine Trump over $370 million to disgorge profits from what James says is a decade of fraudulent business conduct, and to bar Trump for life from participating in the New York real estate industry.

The request for a $370 million fine, plus 9% annual interest, is a sharp increase from James' initial request for disgorgement totaling roughly $250 million.

The largest portion of the requested fine stems from the business loans the Trump Organization obtained using allegedly fraudulent financial statements. Based on expert testimony, James argued that Trump cost his lenders $168,040,168, which the banks would have made if Trump was given the appropriate interest rate corresponding to the actual value of his assets.

In their defense filing, Trump's lawyers called the attorney general's theory for disgorgement "fundamentally flawed, saying that "No lenders testified that they would have done anything differently had they known about Trump's misstatements, and James attempted to fill that evidentiary void with expert testimony, according to Trump's lawyers.

Trump's lawyers added that even if the attorney general proved that some of Trump's profits were ill-gotten, they lack the authority under New York Executive Law 63(12) to request the disgorgement.

Closing arguments in the trial are scheduled for Jan. 11.

The second day of testimony from the defense's expert accounting witness prompted an argument between attorneys for the two sides over the basic question of what the case is about -- leading defense lawyers to make their fourth unsuccessful request for a directed verdict to end the trial.

The arguments came toward the end of direct testimony by accounting expert defense Eli Bartov, who asserted the New York attorney general's case lacked merit because there was no evidence of any fraud on Trump's statements of financial condition, and that any errors about the values of Trump's properties were unintentional and therefore immaterial.

When the defense attempted to question Bartov about those values, state attorneys objected -- prompting defense attorney Christopher Kise to leap from his seat.

"If they don't call anyone to dispute our values, how have they proven their case?" Kise said.

Judge Arthur Engoron, in a pretrial ruling, already decided that Trump conducted a decade's worth of business using fraudulent financial statements, and state attorney Kevin Wallace suggested that Bartov's findings do not change those findings.

"You can't use false statements in business. That's what the summary judgment decision is all about. I think it is pretty much what the rest of this case is about," Engoron said in response to Kise's question.

Kise argued that if the attorney general doesn't prove what Trump's asset values should have been, the case is a "completely rudderless ship" that needs to be "moored to some sort of standard."

"You can't just say it's a misstatement because you feel like it," Kise argued.

"The standard is truth," Engoron responded.

The exchange prompted Trump's legal spokesperson, Alina Habba, to make the defense's fourth motion for a directed verdict, arguing that Engoron is "wasting our time" if he won't consider their expert testimony.

"They have not proven their case. They haven't," Habba said in her request for a directed verdict.

"Denied," Engoron said within seconds of the request, without hearing a response from lawyers for the New York attorney general.
