Members of Donald Trump's legal team, speaking to reporters outside the courthouse prior to the start of the trial, called the fraud allegations against the former president "election interference."

Trump's attorneys said that Democrats were using the case to fight Trump's efforts to retake the White House in 2024.

New York Attorney General Letitia James has arrived at the courthouse in lower Manhattan.

"No matter how powerful you are, no matter how much money you think you may have, no one is above the law," James said to the cameras before entering the courthouse.

"Today we will prove our case in court," she said. "Justice will prevail."

Demonstrators across the street from the courthouse cheered and applauded as the AG arrived.

New York Attorney General Letitia James released a statement on Monday just hours before the first day of trial in her fraud case against former President Donald Trump.

"For years, Donald Trump falsely inflated his net worth to enrich himself and cheat the system," James said. "We won the foundation of our case last week and proved that his purported net worth has long been rooted in incredible fraud. In this country, there are consequences for this type of persistent fraud, and we look forward to demonstrating the full extent of his fraud and illegality during trial."

"No matter how rich or powerful you are, there are not two sets of laws for people in this country," she added. "The rule of law must apply equally to everyone, and it is my responsibility to make sure that it does."

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?"
