Ford and Kavanaugh did not attend the same high school—he went to an all-boys Catholic high school and she attended an all-girls (non-Catholic) high school. Kavanaugh said they weren’t in the same social circle but wasn’t sure if they had met. I don’t know if any evidence has been put forward (other than Ford’s allegations—hardly “evidence”) that they knew each other at all in high school. Her friend who was supposedly at the party had never met Kavanaugh.
