After Firing Matt Lauer, NBC Executives Move to Control the Damage

The top two executives at NBC News tried to quell any in-house suspicions on Friday concerning their handling of Matt Lauer, the longtime “Today” show star who was fired on Tuesday.

Their communications with staff members came after competing media organizations had expressed skepticism about the official NBC denial. The network had said on Wednesday that its executive ranks had not been aware of Mr. Lauer’s alleged sexual misconduct involving female colleagues until they had learned of a detailed complaint on Monday.

Noah Oppenheim, the news division’s president, met with “NBC Nightly News” staff members at their daily meeting to tell them about recent conversations that took place between Mr. Lauer and NBC News executives.

According to an NBC employee who was present at the meeting and spoke about it on condition of anonymity to discuss internal issues, Mr. Oppenheim said that four executives — including himself and Andrew Lack, the NBC News chairman — had asked Mr. Lauer repeatedly in recent weeks if he had engaged in inappropriate behavior with staff members and that he had denied any wrongdoing.

Mr. Oppenheim said that in recent years he had been aware of articles in supermarket tabloids alleging that Mr. Lauer had extramarital affairs, but that was the extent of his knowledge of anything potentially inappropriate in the former host’s off-camera life, the person said.

Mr. Oppenheim added that NBC executives began their questioning of Mr. Lauer after learning that reporters from The New York Times and Variety were looking into Mr. Lauer’s workplace conduct.

In a memo sent to NBC staff members on Friday afternoon, Mr. Lack addressed “the circumstances around Matt Lauer’s appalling behavior, why this was able to happen, and why it wasn’t reported sooner.”

Mr. Lack said that a “team of the most experienced NBCUniversal Legal and Human Resources leaders have begun a thorough and timely review of what happened” regarding Mr. Lauer. (When Fox News faced public allegations of sexual misconduct against its chairman, Roger Ailes, and one of its prime time stars, Bill O’Reilly, it hired the outside law firm Paul, Weiss, Rifkind, Wharton & Garrison to conduct a review.)

Mr. Lack further pledged in the memo that the network would have “greater transparency” in the future. He also directed NBC News employees to take any complaints to their managers, newsroom leaders, human resources officers or two available hotlines, the NBCUniversal Integrity Helpline and the Comcast Listens Helpline.

On Wednesday, in the memo announcing Mr. Lauer’s firing, Mr. Lack said that the detailed allegation made against Mr. Lauer on Monday was “the first complaint about his behavior in the over twenty years he’s been at NBC News.”
