Summer Zervos, a former Apprentice contestant who accuses Donald Trump of assault, has filed a defamation lawsuit against the president-elect.

She alleges Donald Trump forced himself on her in 2007.

The lawsuit, which Summer Zervos announced at a news conference, alleges Donald Trump is a “liar and misogynist” who “debased and denigrated” her.

The news came just three days before Donald Trump is sworn in as president.

Donald Trump faced a spate of misconduct allegations in the run up to the election, all of which he has denied.

At the time, he dismissed them as “false and ridiculous” and said they were “sick” and driven by fame, money or politics.

“Since Mr. Trump has not issued a retraction, as I requested, he has therefore left me with no alternative but to sue him in order to vindicate my reputation,” Summer Zervos told journalists in LA on January 17.

The former Apprentice contestant was joined by her lawyer, Gloria Allred, a Democratic Party activist, who said the plaintiff’s allegations had passed a lie detector test.

Summer Zervos, 41, is one of several women who came forward to accuse the incoming 45th president of assault after the October release of a 2005 videotape in which he is heard making lewd comments about groping women.

The former reality show contestant said Donald Trump had assaulted her during a meeting to discuss job opportunities at a Beverly Hills hotel.

Donald Trump has not filed a lawsuit against any of the women, despite an earlier threat to sue the accusers.

Summer Zervos’ lawsuit alleges that Donald Trump defamed her by denying her account and accusing her and other women of fabricating assault claims.

She asked the president-elect to retract his words late last year, but he declined to do so.

Gloria Allred said Donald Trump “knowingly, intentionally and maliciously threw each of these women under the bus” and that repeatedly calling them “liars” in public caused distress.

Summer Zervos added that she would be willing to rescind the lawsuit if Donald Trump retracts the statements he made and acknowledges his behavior towards her.

Following her allegations, the Trump campaign released a statement from someone it identified as Summer Zervos’ first cousin.

John Barry wrote that he was “shocked and bewildered” by her allegations, insisting Summer Zervos had only previously said “glowing” things about Donald Trump.
