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.

A lawyer for New York Attorney General Letitia James, in a court filing Wednesday, argued in favor of maintaining the judge's limited gag after an appeals court temporarily lifted the order last week.

The limited gag order, which prohibited Donald Trump and his attorneys from publicly commenting about Judge Arthur Engoron's staff, was issued by the judge last month after Trump posted about the judge's law clerk on social media. Judge David Friedman of the appellate division's First Department stayed the order on Thursday, citing constitutional concerns over Trump's free speech rights.

James' court filing Wednesday alleges that Trump and his lawyers continue to harass Engoron’s law clerk "as part of an improper tactic to disrupt trial and undermine the proceedings."

James said the gag order is a necessary and "exceedingly limited restraint" to protect Engoron’s staff, and Trump’s lawyers failed to prove that attacks on judicial staff during a trial are protected by the First Amendment.

"A speedy denial is necessary to ensure the safety of [the] Supreme Court's staff and the integrity and the orderly administration of the proceedings through the end of the trial," James wrote, describing Trump's attacks as "extraordinary and dangerous."

Arguing that Trump has engaged in a "pattern" of attacking civil servants involved in proceedings against him, James cited his attacks on the former lieutenant governor of Georgia, as well as officials in his federal election interference case. She also mentioned Trump’s renewed attacks against the clerk over the last week since the gag order was lifted, including calling for her prosecution, sharing an article suggesting she engaged in drug use, and describing her as "crooked and highly partisan."

Trump's lawyers have defended such attacks as constitutionally protected speech and argued that Engoron failed to articulate how the attacks present a "clear and present danger" to the clerk.

Trump personally sued Engoron last week using a provision of state law called Article 78, which is generally used to challenge New York government agencies. Trump unsuccessfully attempted to use an Article 78 proceeding on the eve of the trial to delay the proceeding; however, his most recent attempt successfully resulted in a temporary stay of the gag order.

Trump's reply to the filing is due on Nov. 27, after which the First Department will decide whether to fully lift the gag order.
