But while we found Dr. Ford’s allegations credible during a 10-month investigation, Ms. Ramirez’s story could be more fully corroborated. During his Senate testimony, Mr. Kavanaugh said that if the incident Ms. Ramirez described had occurred, it would have been “the talk of campus.” Our reporting suggests that it was.

At least seven people, including Ms. Ramirez’s mother, heard about the Yale incident long before Mr. Kavanaugh was a federal judge. Two of those people were classmates who learned of it just days after the party occurred, suggesting that it was discussed among students at the time.

We also uncovered a previously unreported story about Mr. Kavanaugh in his freshman year that echoes Ms. Ramirez’s allegation. A classmate, Max Stier, saw Mr. Kavanaugh with his pants down at a different drunken dorm party, where friends pushed his penis into the hand of a female student. Mr. Stier, who runs a nonprofit organization in Washington, notified senators and the F.B.I. about this account, but the F.B.I. did not investigate and Mr. Stier has declined to discuss it publicly. (We corroborated the story with two officials who have communicated with Mr. Stier.)
