LOS ANGELES - NBC is standing firm against giving fired Today host Matt Lauer a payout on the multimillion-dollar salary he's leaving behind, according to a person at the network. Lauer, said to have earned around $25 million a year, reportedly is negotiating to receive the remainder of his salary for the current contract that runs through 2018 and made him one of TV's highest-paid journalists. But NBC won't agree, said the person, who spoke on condition of anonymity because a personnel matter was involved. Some NBC News employees who raised the question of Lauer's compensation at a staff meeting were told that he was fired for cause and wouldn't be paid beyond his last day worked, according to a Variety report Sunday. Also, NBC News Chairman Andrew Lack said an internal review into Lauer's alleged sexual misconduct is underway, including how it happened and why it wasn't stopped earlier. In a company-wide memo released publicly, Lack said those are among the questions NBC employees are asking in the wake of the Today host's firing for what Lack labeled appalling behavior. A team of NBCUniversal legal and human resources leaders have started a thorough and timely review of what occurred and how the company can foster greater transparency and mutual respect, Lack said in the memo. At the conclusion of the review we will share what we've learned, no matter how painful, and act on it, he said. NBC's announcement Tuesday that Lauer was being fired for inappropriate sexual behavior meant that the network was cutting loose the popular, long-established star of its highly lucrative morning show. In his first public response, Lauer said in a statement Friday that some of the allegations were untrue but others had enough truth that he felt embarrassed and ashamed. Repairing the damage caused is his full-time job, Lauer said. - AP
