Again, no evidence that it even happened.
From the NY Times:
In a statement, Judge Kavanaugh denied the allegation from the woman, Deborah Ramirez, and called it “a smear, plain and simple.” The New Yorker did not confirm with other eyewitnesses that Judge Kavanaugh was at the party.
The Times had interviewed several dozen people over the past week in an attempt to corroborate her story, and could find no one with firsthand knowledge. Ms. Ramirez herself contacted former Yale classmates asking if they recalled the incident and told some of them that she could not be certain Mr. Kavanaugh was the one who exposed himself.
