New York City ? 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.

Bob Schieffer said, “All of us are praying for the best, and our thoughts are with Walter’s family.” The host of CBS’ “Face the Nation” and a longtime Cronkite colleague, Schieffer noted that he had no current news on Cronkite’s condition.

The face of CBS News for more than two decades, Cronkite was named “the most trusted man in America” in a 1972 “trust index” survey, and he ended each broadcast with the reassuring signoff, “And that’s the way it is.”
