New Book Says NBC Knew of Other Lauer Misconduct Before Firing Him

Ronan Farrow made his first TV appearance Friday since excerpts from his upcoming book, "Catch and Kill," revealed new details surrounding Matt Lauer's 2017 firing.

Farrow, on "Good Morning America," told George Stephanopoulos he stands by his book, which is out next week, despite Lauer calling the reporting in "Catch and Kill" false and defamatory. While on the morning show, Farrow also alleged there were previous accusations brought to NBC regarding Lauer's conduct, prior to the 2017 complaint that led to his ouster.

In a meeting with NBC officials in November 2017, former NBC News producer Brooke Nevils "unambiguously" described being raped by former "Today" host Matt Lauer without explicitly using that term, investigative journalist Ronan Farrow said in a television interview Friday.

The claim is included in "Catch and Kill," an upcoming book by Farrow that documents his reporting on movie mogul Harvey Weinstein and other prominent men who are accused of attacking and harassing women. NBC News has not seen a copy of the book, slated to be released on Tuesday.
