Watch Video: Gloria Allred Press Conference With Donald Trump Accuser

LOS ANGELES, CA — Summer Zervos, a contestant on season five of "The Apprentice," is suing Donald Trump, accusing the president-elect of defamation for calling her a liar when he denied during the presidential campaign that he sexually abused her.

High-powered civil rights attorney Gloria Allred announced the defamation lawsuit filed in New York at a Los Angeles press conference Tuesday. The suit stems from an October news conference in which Zervos said Trump twice kissed her on the lips in his New York office in 2007 and groped her breast following a dinner at the Beverly Hills Hotel. Trump issued a statement denying ever meeting Zervos in private, claiming to have only a vague recollection of her.

Zervos said that since she came forward in October, she’s been bullied and threatened by Trump and his supporters.

“Mr. Trump stated that after the election he would file lawsuits against me and the other accusers he sexually assaulted,” she said. “I also suffered other repercussions because I chose to speak out and tell the truth.”

"I also called up on him to state that what I said about his behavior toward me was true," Zervos added. "More than two months have gone by, and he has not issued that retraction. I wanted to give Mr. Trump the opportunity to retract his false statements about me and the other women who came forward. Mr. Trump has not issued a retraction as I requested, he has therefore left me with no alternative other than to sue him in order to vindicate my reputation. I want Mr. Trump to know that I will still be willing to dismiss my case against him immediately for no monetary compensation if he would simply retract his false and defamatory statements about me and acknowledge that I told the truth about him."

Describing Zervos as “a woman who had the fortitude and courage to come forward and speak truth to power so the nation would be informed,” Allred said Zervos passed a lie detector test, attesting to her credibility.

“Truth matters. Women matter. Those who alleged the were victims of sex misconduct or sex assault by Donald Trump matter,” added Allred. "Mr. Trump knew that his false, disparaging statements would be heard by people around the world."

Allred represented several Trump accusers during the presidential election. Her clients came forward to accuse Trump shortly after an infamous "Access Hollywood" tape was made public in which he bragged about groping women without their permission.

A spokeswoman for the Trump campaign has not returned Patch’s calls for comment.

In October, he refuted Zervos' account.

"I vaguely remember Ms. Zervos as one of the many contestants on The Apprentice over the years," he said in a written statement. "To be clear, I never met her at a hotel or greeted her inappropriately a decade ago. That is not who I am as a person, and it is not how I’ve conducted my life. In fact, Ms. Zervos continued to contact me for help, emailing my office on April 14th of this year asking that I visit her restaurant in California."

Throughout the campaign, Allred represented women who accused Trump of unwanted kissing, groping and sexual harassment, and she dared him to release his employees from nondisclosure clauses.

Zervos said she was motivated to come forward after he denied sexually abusing women during a presidential debate. In October, Zervos accused Trump of becoming aggressive with her when she met with him in 2007 in hopes of getting a job with his company.

"When I arrived he kissed me on the lips," Zervos said. "I was surprised, but felt that perhaps that was just his form of greeting."

She said Trump was complimentary to her during the meeting and said that he would "love to have me work for him," and told her he would contact her during an upcoming trip to Los Angeles.

"As I was about to leave he again kissed me on the lips," she said. "This made me feel very nervous and embarrassed. This is not what I wanted or expected."

She said she returned to Los Angeles, and Trump contacted her and asked her to meet him at the Beverly Hills Hotel. Trump's security team met her at the hotel and led her to a bungalow, where she sat in the living room and waited for about 15 minutes until Trump entered the room.

"I stood up and he came to me and started kissing me open-mouthed as he was pulling me towards him. I walked away and I sat down on a chair. He was on a love seat across from me and I made an attempt at conversation.

"He then asked me to sit next to him. I complied. He then grabbed my shoulder and began kissing me again very aggressively, and placed his hand on my breast. I pulled back and went to another part of the room. He then walked up, grabbed my hand and walked me into the bedroom.

"I walked out. He then turned me around and said, 'Let's lay down and watch some telly telly.' He put me in an embrace, and I tried to push him away. I pushed his chest to put space between us, and I said, 'Come on man, get real.' He repeated my words back to me, 'Get real,' as he began thrusting his genitals. He tried to kiss me again with my hand still on his chest and I said, 'Dude you're tripping right now,' attempting to make it clear that I was not interested.'"

She said Trump appeared to become angry, and as they waited for dinner, "He started saying that he did not think that I had ever known love or had been in love."

After the dinner and some conversation about a job and Trump offering advice about getting out of her mortgage, he "abruptly said that he was tired and that he needed to go to bed."
