Matt Lauer was fired from NBC News on Wednesday after an employee filed a complaint about "inappropriate sexual behavior in the workplace," the network announced.
Savannah Guthrie made the announcement at the top of the "Today" show, where Lauer has been an anchor for two decades.
NBC News chairman Andrew Lack said in a memo to staff that it was the first complaint lodged against Lauer in his career at the network. But he said "we were also presented with reason to believe this may not have been an isolated incident."
Just last week, CBS News fired one of its own morning anchors, Charlie Rose, after a report in The Washington Post chronicled years of sexual misconduct.
