Two New York Times reporters say they’ve uncovered a previously unreported account of sexual misconduct allegedly carried out by Supreme Court Justice Brett Kavanaugh when he was a student at Yale.

In an op-ed for the Times, Robin Pogrebin and Kate Kelly said they learned of the alleged misconduct during a 10-month investigation of Kavanaugh’s life at prep school and Yale, including the assault accusations, for their upcoming book, “The Education of Brett Kavanaugh: An Investigation.”

According to Pogrebin and Kelly, Max Stier, a classmate of Kavanaugh’s at Yale, told senators and the FBI that he once saw Kavanaugh with his pants down while his friends pushed his penis into the hands of a female student during a dorm party.

The FBI didn’t investigate Stier’s account, and Stier “has declined to discuss it publicly,” according to the Times. However, Pogrebin and Kelly said they “corroborated the story with two officials who have communicated” with Stier.

What Stier said he witnessed is similar to an allegation lodged against Kavanaugh by his former classmate Deborah Ramirez, which was first reported by The New Yorker’s Ronan Farrow last September.
