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.

Day 14 of the proceedings gets underway following a motion filed late Thursday by Ivanka Trump that seeks to quash three subpoenas that would compel her to testify in the trial.

Donald Trump's eldest daughter, who was no longer a part of the Trump Organization by 2016, was dismissed from the civil suit by an appeals court in June.

But the New York attorney general still plans to call her as a witness in the state's case. In early September, the AG sent subpoenas to three corporate entities affiliated with Ivanka Trump to force her to testify in person.

"The NYAG, which never deposed Ms. Trump, is effectively trying to force her back into this case from which she was dismissed by a unanimous decision of the Appellate Division, First Department," Ivanka Trump's lawyer, Bennet Moskowitz, wrote in Thursday's filing.

Moskowitz argued that the subpoenas should be thrown out since they were not properly served and because the AG lacks jurisdiction to force Ivanka Trump, who is no longer a New York resident, to testify.

"The NYAG knows this, which is why it has subpoenaed three corporate entities as an end-run around its failure to pursue Ms. Trump's deposition when it had the chance," the filing said.

In a Thursday email that was entered as an exhibit to the motion, a lawyer for the attorney general's office indicated they do not plan to request Judge Arthur Engoron hold Ivanka Trump in contempt. They instead plan to file a motion today to compel her to appear in court, according to the email.
