NEW YORK - "Today" show host Matt Lauer has been terminated by NBC.

The announcement was made at the opening of Wednesday morning's show by co-host Savannah Guthrie.

New York Times reporter Jim Rutenberg says in a tweet Wednesday morning that a memo released from NBC News Chairman Andrew Lack said there was “complaint from colleague about inappropriate sexual behavior in the workplace by Matt Lauer.” Lack stated this was the first complaint lodged against Lauer, but added "we were also presented with reason to believe this may not have been an isolated incident."
