According to legal documents obtained by USA media, Ms Tennant met Mr Walton in his suite at the Hotel Casa Del Mar in Santa Monica to give him a copy of her 2014 book. At a news conference Tuesday, she detailed the alleged assault by Walton at a Santa Monica hotel room in the fall of 2014, when he was an assistant coach for the Golden State Warriors.
Tennant said Walton, whom she considered to be a longtime friend and mentor, had written the foreword to a 2014 book she had written. Tennant says she asked to meet up and give him a copy of the book while the team was in Los Angeles.
Tennant claims Walton finally released her, allowing her to leave.
"He got on top of me and pinned me down to the bed, and held my arms down, with all of his weight, while he kissed my neck and my face and my chest", she said.
The lawsuit says he eventually stopped and let her go but, as she walked away, he grabbed her from behind and again forced himself on her.
Tennant says she pleaded with him to stop, but that Walton kept holding her down.
Tennant revealed she didn't come forward with the story because she was only 25 at the time and scared.
"Every interaction with him that I've had made me incredibly uncomfortable and feel unsafe", she said.

The names and ages of the victims were not made available at first, as the family is known to keep a low profile. Warnings have been issued about possible further attacks on the island in the Indian Ocean.
Luke Walton's attorney calls the allegations "baseless" and Tennant "an opportunist not a victim".
After discussing the book, she said Walton pinned her to his bed, fondling and kissing her. "We intend to prove this in a courtroom". Tennant says in the suit that Walton continued to make unwanted advances toward her following the alleged incident.
It is not uncommon for sexual assault victims to feel powerless and not come forward for years, particularly in high-profile cases where they know the public nature and the backlash that will follow - regardless of truth - from the accusations. "I have spent years now dealing with this, trying to forget it about it, hoping that I could push it to the side and bury it, and hoping that time would heal", she said.
Garo Mardirossian, Tennant's lawyer, told the Times he would share further information in a news conference and declined to say whether Tennant had reported the alleged assault to police.
When asked what they want to get out of the case, Tennant's attorney says they have no particular sum in mind. She now does a wellness podcast.
'Aided by their fame, money and power, and motivated by a culture that tolerates misogynistic gender-bias, too many men in professional basketball inappropriately abuse women, ' he said in a statement issued before the news conference.
The NBA added this statement, per multiple reports: "We are coordinating with the Kings organization and are in the process of gathering more information". "We have no further comment at this time". The Los Angeles Police Department has stated that it was never informed of any allegations against Walton, who at the time was an assistant coach with the Golden State Warriors.
'If it had been, we would have immediately commenced an investigation and notified the National Basketball Association, ' the Lakers said, declining further comment. Walton played for the Lakers from 2003 to 2012. He later became head coach of the Kings two days later.
