Huma Abedin, a longtime aide to Hillary Clinton and ex-wife of former New York Congressman Anthony Weiner, wrote in her upcoming memoir about a sexual assault in her 20s by an unnamed U.S. senator.

In her book, Both/And: A Life in Many Words, she describes an incident where the unidentified senator kissed her during a meeting in his apartment and forced his tongue into her mouth. According to The Guardian, who received her memoir excerpt, she withheld all information to identify the senator, including even his party affiliation, what state his represented, and whether or not he is still a sitting member of the Senate.

After a Washington D.C. dinner with several lawmakers, who were also unnamed, Huma Abedin and the alleged senator walked to his apartment, where she reportedly went up to have coffee.

He “told me to make myself comfortable on the couch,” she wrote. “Then, in an instant, it all changed. He plopped down to my right, put his left arm around my shoulder, and kissed me, pushing his tongue into my mouth, pressing me back on the sofa.”

Abedin recalled how she was “so utterly shocked,” and pushed the senator away. “All I wanted was for the last 10 seconds to be erased,” she said.

According to her memoir, the senator then apologized and said that he had “misread” the situation “all this time” and wanted to make it up to her “without this ending badly.”

“Then I said something only the twenty-something version of me would have come up with—‘I am so sorry’—and walked out, trying to appear as nonchalant as possible,” Huma Abedin described.

Abedin, 45, worked as an aide for Hillary Clinton at the time of the incident, while she was Senator of New York from 2001 to 2009 alongside longtime sitting senator and now Senate Majority Leader Chuck Schumer. Abedin was later deputy chief of staff for Clinton during her tenure as U.S. Secretary of State from 2009 to 2013, and then she was vice chair of her 2016 Presidential campaign.

According to Huma Abedin, she ran into the unidentified senator a few days later while out with Hillary Clinton on Capitol Hill, where the senator apologized once more and asked if they could still be friends following the incident.

In her memoir, Abedin wrote that Clinton intervened in the conversation, “as if she knew I needed rescuing even though I’d told her nothing about that night.”

She later wrote that her and the senator remained friendly and she “buried the incident” in her memory until 2018 when Christine Blasey Ford openly testified against Supreme Court Justice Brett Kavanaugh.

The Senate hearings allegedly “triggered” her into remembering the sexual assault, though she had decided to not release the name of the individual involved.

In 2010, at Abedin’s wedding to former-congressman Anthony Weiner, Hillary Clinton toasted the couple saying, “I have one daughter. But if I had a second daughter, it would [be] Huma.”

The marriage ended in 2017, when the two separated following Anthony Weiner’s disgraced sexting scandal with a minor, to which he plead guilty. According to The Daily Beast, he was sentenced to 21 months in prison and was released after serving 18.

“The first thing out of my mouth wasn’t ‘How could you do this to me?’ or ‘I thought that you loved me,'” she wrote in her memoir. “The first thing I said was, ‘You mean you’ve been lying to the whole world for a week? Anthony, you have people counting on you. You owe them the truth!'”

“I know,” he allegedly said. “I have to go back and deal with the consequences.”

Human Abedin’s memoir Both/And: A Life in Many Words is expected to be released on Nov. 2.
