Former President Donald Trump and New York Attorney General Letitia James, in separate media appearances, addressed the ruling Friday evening, trading barbs while reacting to the judgment.

Speaking from his Mar-a-Lago estate in Florida, Trump said he had to pay a fine for "having built a perfect company." Accusing both James and Judge Arthur Engoron of being politically motivated, Trump denied committing any fraud and said he plans to appeal.

Meanwhile, in New York, James lauded the ruling as a victory for all Americans and the principles of equal justice under the law -- saying "former presidents are no exception."

"The scale and scope of Donald Trump's fraud is staggering -- and so, too, is his ego and his belief that the rules don't apply to him," she said.

James also heralded Judge Engoron's penalties as effective remedies to "ensure this fraud cannot continue."

Based on Friday's decision, former President Trump and his co-defendants will likely owe $463.9 million based on their initial fine and the prejudgment interest imposed by the court, according to a representative for the New York attorney general.

Trump himself will likely owe $453.5 million, between his $354.86 million fine and $98.6 million in interest.

The amount of interest owed by the defendants is set to increase every day they do not pay the fines.

New York Attorney General Letitia James, whose office brought the civil fraud case against Donald Trump, described the ruling as a "tremendous victory for this state, this nation, and for everyone who believes that we all must play by the same rules -- even former presidents."

“When powerful people cheat to get better loans, it comes at the expense of honest and hardworking people," James said in a statement. "Everyday Americans cannot lie to a bank to get a mortgage to buy a home, and if they did, our government would throw the book at them. There simply cannot be different rules for different people."

The former president is "finally facing accountability for his lying, cheating, and staggering fraud," she said.

In addition to the fines imposed on Donald Trump and his co-defendants, the judge's decision leaves the Trump Organization in a constrained position to continue operating their New York-based businesses.

While Judge Engoron backtracked on his September summary judgment ruling -- vacating the part of his order that canceled their business certificates -- Donald Trump and his sons are temporarily unable to lead their namesake company. Trump faces a three-year ban on serving as the leader of a New York company, and his sons face two-year bans.

An independent monitor will continue to oversee the company's finances for at least three years, and the company needs to install a director of compliance.

Regarding the combined $364 million owed by the defendants, experts who ABC News spoke with believe it is unlikely any of them foot the bill immediately; instead, they can cover the fine with a bond while they appeal.

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?"
