The woman at the center of the story, Deborah Ramirez, who is fifty-three, attended Yale with Kavanaugh, where she studied sociology and psychology. Later, she spent years working for an organization that supports victims of domestic violence. The New Yorker contacted Ramirez after learning of her possible involvement in an incident involving Kavanaugh.

Ramirez said that, when both she and Kavanaugh were freshmen at Yale, she was invited by a friend on the women’s soccer team to a dorm-room party. She recalled that the party took place in a suite at Lawrance Hall, in the part of Yale known as Old Campus, and that a small group of students decided to play a drinking game together. “We were sitting in a circle,” she said. “People would pick who drank.” Ramirez was chosen repeatedly, she said, and quickly became inebriated. At one point, she said, a male student pointed a gag plastic penis in her direction. Later, she said, she was on the floor, foggy and slurring her words, as that male student and another stood nearby. (Ramirez identified the two male onlookers, but, at her request, The New Yorker is not naming them.)

A third male student then exposed himself to her. “I remember a penis being in front of my face,” she said. “I knew that’s not what I wanted, even in that state of mind.” She recalled remarking, “That’s not a real penis,” and the other students laughing at her confusion and taunting her, one encouraging her to “kiss it.” She said that she pushed the person away, touching it in the process. Ramirez, who was raised a devout Catholic, in Connecticut, said that she was shaken. “I wasn’t going to touch a penis until I was married,” she said. “I was embarrassed and ashamed and humiliated.” She remembers Kavanaugh standing to her right and laughing, pulling up his pants. “Brett was laughing,” she said. “I can still see his face, and his hips coming forward, like when you pull up your pants.” She recalled another male student shouting about the incident. “Somebody yelled down the hall, ‘Brett Kavanaugh just put his penis in Debbie’s face,’ ” she said. “It was his full name. I don’t think it was just ‘Brett.’ And I remember hearing and being mortified that this was out there.”

Ramirez acknowledged that there are significant gaps in her memories of the evening, and that, if she ever presents her story to the F.B.I. or members of the Senate, she will inevitably be pressed on her motivation for coming forward after so many years, and questioned about her memory, given her drinking at the party.
