Some suggested it damages the report's credibility. "No one is going to be fully candid when speaking to management for fear of losing their jobs". But Curry specifically named Lauer as a person of concern.
NBC's decision to have the investigation led by its own general counsel drew criticism.
NBC has concluded its investigation after Matt Lauer was sacked from the Today show in November due to alleged sexual misconduct in the workplace. "Throughout the two weeks after Lauer's termination was introduced publicly by NBC Information on November 29, 2017, the Firm obtained details about three further girls, who every alleged that Lauer had engaged in inappropriate sexual conduct within the office with them in 2000, 2001 and 2007, respectively".
The investigation, which was led by NBCUniversal general counsel Kim Harris, focused on Lauer's behavior and complaints from four women, who came forward late previous year.
The report countered a claim by former "Today" anchor Ann Curry, who said she reported Lauer's misconduct in 2012.
ET obtained the report on Wednesday, which says that the investigation team found four women's allegations that the 60-year-old anchor engaged in inappropriate sexual behavior in the workplace to be credible, but that they also found credible the statements from those in leadership positions that they were unaware of his behavior. During a subsequent interview, Lauer "admitted to engaging in sexual activity with the complainant".
One month before in October 2017, the New York Times published an expose about Weinstein Company founder, Harvey Weinstein, that revealed he had sexually harassed several women throughout his long-running career.
NBC also addressed Lauer's now-infamous "button", a device under his desk that allowed him to close his office door without standing up.More news: Saudi Arabia set to pursue nuclear weapons if Iran restarts program

"I've made no public feedback on the various false tales from nameless or biased sources which have been reported about me over these previous a number of months - together with a declare that I'd, and even might, lock somebody in my workplace", he continued.
The company said it remains interested in hearing from other women who experienced sexual misconduct by Lauer. Most were already known and dealt with; some are being looked into, the report said.
NBC was slammed on Twitter Wednesday after it conducted an internal investigation into how the network handled allegations of sexual harassment against Matt Lauer and found there is "no evidence" any NBC senior executives knew about Lauer's behavior.
Lauer admitted to the allegation in an interview with NBC's legal and human-resources staff on November 28, the report said. Harris consulted two outside law firms.
"The last few months have been extraordinarily hard, with our dedicated journalists doing some of our best work ever while we endured a painful period in the spotlight including a thorough and deserved examination", said NBC Universal Chairman Andy Lack in a memo that was attached to the Laurer investigation report. "But - stepping back from the investigation - that history also includes a time when people were not comfortable coming forward to voice complaints about repugnant behavior. That is not acceptable".
Following Lauer's firing in November over sexual misconduct allegations, NBC launched a probe into his conduct at the network.
But because NBC News is seen as ideologically pure, issues like honesty, decency, and integrity are seen as meaningless.
