NEW YORK (AP) – CBS will televise a one-hour prime-time tribute to Dan Rather the night he leaves the evening news anchor chair, and its producer says it won’t avoid the story that has clouded his final days on the job.
“Dan Rather: A Reporter Remembers” will air 8 p.m. EST on March 9, an hour after he anchors his final evening newscast after 24 years, the network announced Thursday.
