Attorney Michael Avenatti said Sunday he was representing a woman with "credible information" regarding Supreme Court nominee Brett Kavanaugh and his high school friend Mark Judge. However, he also said his client was not alleged victim Deborah Ramirez — Kavanaugh's second sexual assault accuser.

The news came just minutes before the New Yorker published a story outlining sexual misconduct allegations against Kavanaugh made by a former college classmate.

“We will be demanding the opportunity to present testimony to the committee and will likewise be demanding that Judge and others be subpoenaed to testify,” Avenatti tweeted Sunday night. “The nomination must be withdrawn.”

He also shared a screenshot of the email sent to Mike Davis, the chief counsel for nominations on the Senate Judiciary Committee.

Avenatti claimed he had knowledge that Kavanaugh and Judge targeted women with drugs and alcohol in order to "allow a 'train' of men to subsequently gangrape them." These incidents allegedly took place during "multiple house parties in the Washington D.C. area during the early 1980s."

Avenatti, who represents adult film star Stormy Daniels in a lawsuit against President Donald Trump and has hinted at a possible presidential run, claimed to have “multiple witnesses” that could corroborate “these facts.”

“Each of them must be called to testify publicly,” he said, without naming the source of his evidence nor the alleged victims.

According to the New Yorker story, Ramirez — a Yale classmate of Kavanaugh — claimed he exposed himself to her at a college party. However, Kavanaugh strongly denied that claim as a "smear."

"This alleged event from 35 years ago did not happen. The people who knew me then know that this did not happen, and have said so. This is a smear, plain and simple," Kavanaugh said in a statement Sunday. "I look forward to testifying on Thursday about the truth, and defending my good name — and the reputation for character and integrity I have spent a lifetime building — against these last-minute allegations."

The White House also backed their candidate in a statement Sunday: "This 35-year-old, uncorroborated claim is the latest in a coordinated smear campaign by the Democrats designed to tear down a good man. This claim is denied by all who were said to be present and is wholly inconsistent with what many women and men who knew Judge Kavanaugh at the time in college say. The White House stands firmly behind Judge Kavanaugh."

The New Yorker quoted an ex-girlfriend of Judge’s who said he told her a story that mirrors the allegations Avenatti was making.

Meanwhile, the White House Press Secretary Sarah Sanders issued a news release titled, "What you need to know about the allegations made in the New Yorker article on Judge Brett Kavanaugh."
