NEW YORK — NBC News says longtime "Today" show host Matt Lauer has been fired for "inappropriate sexual behavior."

Lauer's co-anchor Savannah Guthrie made the announcement at the top of Wednesday's "Today" show.

Guthrie read a statement from NBC News chairman Andy Lack, stating that the company has received a detailed complaint from a colleague Monday night "about inappropriate sexual behavior in the workplace" by Lauer. Lack's statement said the company found that after a serious review of the complaint it represented "a clear violation" of the company's standards, and Lauer was terminated as a result.

Lack added in his statement that it was the first complaint about Lauer in more than 20 years at NBC, but "we were also presented with reason to believe this may not have been an isolated incident."

On Twitter Wednesday, President Donald Trump wrote in a Twitter message, "Wow, Matt Lauer was just fired from NBC for 'inappropriate sexual behavior in the workplace.' But when will the top executives at NBC & Comcast be fired for putting out so much Fake News."

Trump then cited the NBC News chairman adding: "Check out Andy Lack's past!" It was not immediately clear what that comment referred to.

The move comes a week after CBS News fired morning anchor Charlie Rose amid reports of sexual misconduct.
