After former Lakers president of basketball operations Magic Johnson stepped down in such stunning fashion on April 9, sources say Walton was given the chance to stay on as head coach in a subsequent meeting that included owner Jeanie Buss.
Former Spectrum Sportsnet reporter Kelli Tennant held a press conference on Tuesday in Los Angeles to address her accusations against Sacramento Kings head coach Luke Walton sexually assaulting her in 2014. Walton worked as a Warriors assistant from 2014-16. The lawsuit was first reported by TMZ.
The legal action says Ms Tennant had viewed Mr Walton as a "trusted mentor and colleague", according to the Los Angeles Times. She drove to the hotel to give him a copy of the book. He invited her to his room so as not to be in the public eye, according to court documents.
Walton's attorney, Mark Baute, also released a statement addressing the lawsuit. "The accuser is an opportunist, not a victim, and her claim is not credible. We intend to prove this in a courtroom", Baute said in a statement to CNN Sports.
"We are aware of the report and are gathering additional information", the Kings said.
The Los Angeles Lakers statement said the alleged incident took place before he became their head coach.
"At no time before or during his employment here was this allegation reported to the Lakers", the team said.
Both the National Basketball Association and the Kings have launched investigations into the matter. The team later said in a statement that the incident occurred before Walton was an employee and it indeed wasn't reported to them.
The Warriors were similarly unaware, they said.
The Warriors said the team was "in the process of seeking more information" and had no further comment. "We'll have no further comment at this time".
No date is given for the alleged assault.
Mr Walton had written the foreword to the publication, The Transition: Every Athlete's Guide to Life After Sports. Walton played for the Lakers from 2003 to 2012.
Tennant knew Walton from when he covered the Lakers as a Sportsnet analyst.
Local broadcaster Kelli Tennant has launched a lawsuit against Kings coach Luke Walton. He was quickly named coach of the Sacramento Kings.
The article goes into further detail, alleging that Walton went on to grope her breasts and groin before leaving the room.
Luke Walton and the Los Angeles Lakers had a tumultuous relationship this year, especially with the addition of LeBron James to the roster.
Luke Walton was accused of sexual assault in a lawsuit that was filed on Monday, but the allegation against the coach never made its way to law enforcement.
Because of her job, Tennant continued to have regular contact with Walton. She now hosts a podcast. She says she screamed and tried to get up, but he pinned her in place. "That has really gotten me through it".
