A woman claimed on social media Tuesday that she had heard about an alleged sexual assault by Brett Kavanaugh, now a Supreme Court nominee, when they were teens in the 1980s.

She has deleted her posts, but Cristina King Miranda confirmed to NPR that she remembered hearing “buzz” in high school about an unusually serious incident at a party.

Kavanaugh’s accuser, Christine Blasey Ford, came forward Sunday in a Washington Post story. She said that when they were teenagers, Kavanaugh pinned her to a bed during a party and tried to remove her clothes, covering her mouth with his hand to stifle her screams.

Kavanaugh and Mark Judge, a witness Blasey named, have denied the accusation. Republicans have said there is nothing to corroborate Blasey’s claim.

Early on Tuesday, Miranda said on Twitter she heard about the incident shortly after it happened.

“Christine Blasey Ford was a year or so behind me, I remember her,” Miranda said in a tweet that can still be viewed via the Google cache. “The incident was spoken about for days afterwards in school.”

Blasey told the Post that she hadn’t told anyone about the incident, which she said occurred during a summer party, until 2012.

Miranda deleted her tweet, as well as a lengthier version on Facebook under the name Cristina King, in which she wrote “many of us heard about it in school.” She also said in that post that she had had a crush on Judge.

Miranda’s name is one of the more than 900 on a letter that circulated among alumnae of Holton-Arms ― an all-girls private school in Bethesda, Maryland, that Blasey attended ― supporting her. The letter’s organizers said they verified all the names with a school directory, but a spokesperson for Holton-Arms declined to confirm Miranda had attended.

NBC News reported Wednesday afternoon that it confirmed the social media posts had indeed been posted by the Holton-Arms grad.

Another member of the class of 1983 who signed the letter told HuffPost she didn’t recall hearing about the incident at that time. Members of Blasey’s class of 1984 have written a separate letter supporting their former classmate.

Miranda declined an interview request from HuffPost. In a follow-up tweet, she said she deleted her previous post “because it served its purpose and I am now dealing with a slew of requests for interviews from The Wash Post, CNN, CBS News. Organizing how I want to proceed. Was not ready for that, not sure I am interested in pursuing.”

In another tweet, apparently written before she spoke to NPR, she said she wouldn’t do any media interviews.

“To clarify: I do not have first hand knowledge of the incident that Dr. Christine Blasey Ford mentions, and I stand by my support for Christine. That’s it. I don’t have more to say on the subject.”

Miranda has since deleted her Twitter account entirely.
