Mr. Avenatti had been using his Twitter account for days to promote what he said would be explosive allegations against Judge Kavanaugh. And immediately after he shared what he called a sworn affidavit from Ms. Swetnick, it drew immediate coverage across social media and cable news as another revelation to rock the confirmation process.
In a brief interview, Mr. Avenatti said he had witnesses who could back up Ms. Swetnick’s accounts, but was not ready to present them because he was waiting to see if the Senate Judiciary Committee would begin a full investigation into her claims as he demanded, along with an F.B.I. inquiry. In her statement, Ms. Swetnick said she would be willing to appear before the committee.
Mr. Avenatti also said he was waiting to hear back from the committee before making Ms. Swetnick available for interviews. Asked why Ms. Swetnick would be attending parties with high schoolers during her college years, Mr. Avenatti said that the parties in question included people of both high school and college ages.
In recent days, Judge Kavanaugh and Mr. Trump, who nominated him in July, have been pushing back against the allegations relating to Judge Kavanaugh’s treatment of women. Mr. Trump called the claims a “con game” by Democrats who were “trying to delay and obstruct his confirmation.”
Ms. Swetnick’s allegations come days after Deborah Ramirez, a Yale classmate, told The New Yorker that Judge Kavanaugh exposed himself to her during a drinking game while they were students.
The accusation also comes as Judge Kavanaugh is on the verge of testifying before the Senate Judiciary Committee about an allegation made this month by Christine Blasey Ford, who says he sexually assaulted her in high school. Dr. Blasey, who is sometimes known by her married name, Ford, is also expected to testify.
Ms. Swetnick’s claims included Mark Judge, a classmate of Judge Kavanaugh’s. Mr. Judge, who has written about his alcohol-fueled years at Georgetown Prep, had denied the claim made by Dr. Blasey that he was in the room during the alleged incident when they were teenagers. Barbara Van Gelder, a lawyer for Mr. Judge, said on Wednesday that he denied the allegations in Ms. Swetnick’s statement.
