Trump nemesis Michael Avenatti said Tuesday a third woman with damning allegations against Brett Kavanaugh will reveal her identity and detail her claims when "we have adequate security measures in place." But the attorney also said in a tweet Tuesday that he expects her to go public before Thursday's Senate Judiciary Committee hearing featuring testimony from Kavanaugh and another accuser, Christine Blasey Ford. Ford has claimed the Supreme Court nominee tried to sexually assault her when they were teenagers. Kavanaugh has denied all claims of sexual misconduct. Ford's allegations date to the early 1980s, when she and Kavanaugh were high school students, the same time frame for the accusations by Avenatti's client. "Let me be clear: We will disclose the client's name and accusations only when SHE is ready and we have adequate security measures in place," Avenatti's tweet said. "And not a moment before that. It is her choice and hers alone as to when to surface bc it is her life. We expect it within the next 36 hrs."

Avenatti, who in the past year has become a leading antagonist of President Donald Trump, said last month he was exploring running for the presidency in 2020. Avenatti's client, whom he has called both an accuser and a witness against Kavanaugh, has not been publicly identified. NBC News has not be able to verify her allegations. She would be the third woman, in addition to Ford and Kavanaugh's Yale University classmate Deborah Ramirez, to accused the now 53-year-old federal appellate judge of sexual misconduct as a young man. Avenatti in an email to the Judiciary Committee's chief counsel for nominations outlined his client's allegations. The email said he had knowledge of Washington-area house parties in the early 1980s, when Kavanaugh was in high school, at which Kavanaugh, his pal Mark Judge "and others would participate in the targeting of women with alcohol/drugs in order to allow a 'train' of men to subsequently gang rape them." "There are multiple women that will corroborate these facts, and each of them must be called to testify," Avenatti said. During an interview that aired Monday night on Fox News, Kavanaugh was asked "did you ever participate in any gang rape?" Kavanaugh, his wife by his side, answered: "That's totally false and outrageous, never done such thing, known about such thing." He then said that when he went to Georgetown Prep, an all-boys high school in Maryland, he was focused on "sports and academics, friendship with classmates and all girls school."
