The incident, which occurred in September 1985 during Mr. Kavanaugh’s junior year, resulted in Mr. Kavanaugh and four other men being questioned by the New Haven Police Department. Mr. Kavanaugh was not arrested, but the police report stated that a 21-year-old man accused Mr. Kavanaugh of throwing ice on him “for some unknown reason.”

A witness to the fight said that Chris Dudley, a Yale basketball player who is friends with Mr. Kavanaugh, then threw a glass that hit the man in the ear, according to the police report, which was obtained by The New York Times…

The outlines of the incident were first referred to in a statement issued on Sunday by Chad Ludington, one of Judge Kavanaugh’s college classmates and a member of the Yale basketball team.

“On one of the last occasions I purposely socialized with Brett, I witnessed him respond to a semi-hostile remark, not by defusing the situation, but by throwing his beer in the man’s face,” Mr. Ludington said in the statement. Mr. Ludington, a professor at North Carolina State University, said he came forward because he believed Judge Kavanaugh had mischaracterized the extent of his drinking at Yale.
