The Senate Judiciary Committee says it is reviewing new allegations of sexual misconduct against Supreme Court nominee Brett Kavanaugh.
Attorney Michael Avenatti provided a statement from his client to the committee.
According to a document Avenatti posted on Twitter, the woman alleges she witnessed Kavanaugh "consistently engage in excessive drinking and inappropriate contact of a sexual nature with women in the early 1980s."
The woman also made other accusations in her statement. The AP has not been able to corroborate them, and continues to investigate.
Kavanaugh has been accused of sexual misconduct by two other women, putting his nomination for the high court at risk. He and one of the accusers, Christine Blasey Ford, will testify publicly Thursday before the Judiciary Committee.
Avenatti declined to expand on the allegation in an interview Wednesday on ABC's The View, saying he would not add detail beyond what was in the statement. Avenatti also represents Stormy Daniels, an adult film actress who alleges she was paid to keep quiet about a sexual relationship with President Donald Trump.
Kavanaugh denied the claim on Wednesday.
"This is ridiculous and from the Twilight Zone," he said in a statement released by the White House. "I don't know who this is and this never happened."
Trump also responded on Twitter with an attack on Avenatti. "Avenatti is a third rate lawyer who is good at making false accusations, like he did on me and like he is now doing on Judge Brett Kavanaugh. He is just looking for attention and doesn’t want people to look at his past record and relationships - a total low-life!" he wrote.
