CBS isn't commenting on reports that veteran newsman Walter Cronkite is gravely ill.
The 92-year-old former anchor of "The CBS Evening News," who has been ailing for some time, has reportedly taken a turn for the worse, according to TVNewser and other online sites.
CBS News spokesman Kevin Tedesco had no comment on Friday.
The face of CBS News for more than two decades, Cronkite ended each broadcast with the reassuring signoff, "And that's the way it is."
He left the "Evening News" anchor desk in 1981, but kept a busy schedule in both journalism and other activities after that.
