For its 50th anniversary coverage of the Kennedy assassination, former CBS anchor Dan Rather wasn't invited to partake in his old employer's plans for the occasion, despite being a key reporter in the original incident. He told The Hollywood Reporter it's an attempt by CBS to "airbrush him from history":
"This follows a pattern of some years of, in effect, trying to airbrush me out of their history," he said of CBS. "That doesn’t bother me all that much, nor should it. If anybody is to care about it -- and I’m not sure anybody should -- it’s one thing for the corporation for their own purposes [to not include him in the coverage]. But as a news organization responsible for history, I think the news consumer might want to question whether you want ... corporations trying to change history for their corporate interests."
Rather was, of course, infamously ousted as the anchor and managing editor at CBS News following highly questionable reports on former president George W. Bush‘s military service at the last minute of the 2004 election.
