Former President Donald J. Trump was ordered by a Manhattan jury on Friday to pay $83.3 million to the writer E. Jean Carroll for defaming her in 2019 after she accused him of a decades-old rape, attacks he continued in social media posts, at news conferences and even in the midst of the trial itself.

Ms. Carroll’s lawyers had argued that a large award was necessary to stop Mr. Trump from continuing to attack her. The nine-member jury responded by awarding Ms. Carroll $65 million in punitive damages, finding that Mr. Trump had acted with malice. On one recent day, he made more than 40 derisive posts about Ms. Carroll on his Truth Social website.

On Friday, the judge, Lewis A. Kaplan, called in the jury shortly after 4:30 p.m., cautioning, “We will have no outbursts.” The verdict was delivered nine minutes to utter silence in the courtroom.

Mr. Trump had already left for the day when the dollar figures were read aloud. Hearing the numbers, his lawyers slumped in their seats. The jury was dismissed, and Ms. Carroll, 80, embraced her lawyers. Minutes later, she walked out of the courthouse arm in arm with her legal team, beaming for the cameras.

“This is a great victory for every woman who stands up when she’s been knocked down and a huge defeat for every bully who has tried to keep a woman down,” Ms. Carroll said in a statement, thanking her lawyers effusively.

Mr. Trump, who had walked out of the courtroom earlier during the closing argument by Ms. Carroll’s lawyer, said in a Truth Social post that the verdict was “absolutely ridiculous.”
