She added that “everyone has their own MeToo story,” but “not everyone has the audience or platform to tell their story, and I actually feel like I’m in this very privileged position to be able to do that.”

Ms. Yang said she was assaulted by Robert Hadden, a gynecologist in Manhattan who has since been accused of sexual abuse by multiple patients. She said Mr. Hadden assaulted her in his exam room when she was seven months pregnant.

“I was dressed and ready to go,” she told CNN. “Then, at the last minute, he kind of made up an excuse. He said something about, ‘I think you might need a C-section,’ and he proceeded to grab me over to him and undress me and examine me internally, ungloved.”

Ms. Yang said she was “frozen” during the assault. But she said she later worked with the Manhattan district attorney’s office to build a case against Mr. Hadden and testified before the grand jury that indicted him in 2014 on charges involving six women, including five counts of a criminal sexual act.

In 2016, the office of the district attorney, Cyrus R. Vance Jr., agreed to a plea deal that allowed Mr. Hadden to avoid jail time. Under the agreement, Mr. Hadden gave up his medical license and pleaded guilty to a single felony count of criminal sexual act in the third degree, and one misdemeanor count of forcible touching.
