A Manhattan jury on Tuesday found former President Donald J. Trump liable for sexually abusing and defaming E. Jean Carroll and awarded her $5 million in damages. More than a dozen women have accused Mr. Trump of sexual misconduct over the years, but this is the only allegation to be affirmed by a jury.

In the civil case, the federal jury of six men and three women found that Ms. Carroll, 79, a former magazine writer, had sufficiently proved that Mr. Trump sexually abused her nearly 30 years ago in a dressing room of the Bergdorf Goodman department store in Manhattan. The jury did not, however, find he had raped her, as she had long claimed.

The jury, in returning the verdict shortly before 3 p.m., also found that Mr. Trump, who is running to regain the presidency, defamed Ms. Carroll in October when he posted a statement on his Truth Social platform calling her case “a complete con job” and “a Hoax and a lie.” His lawyer said he intended to appeal.

Mr. Trump’s lawyers called no witnesses, and he never appeared at the trial to hear Ms. Carroll, who had sued him last year, deliver visceral testimony about the attack she said had ended her romantic life forever.

On Tuesday, Ms. Carroll nodded along as a court clerk read the verdict aloud, her nod growing more pronounced as the clerk said Mr. Trump was liable for defamation. She walked out of the courthouse grinning from ear to ear, holding hands with her lawyer, Roberta A. Kaplan. A woman yelled to Ms. Carroll, “You’re so brave and beautiful.” Ms. Carroll replied, “Thank you, thank you so much.”
