Mary Mapes, the longtime CBS news producer who was fired in the wake of the controversy over her Dan Rather-fronted report about George W. Bush's National Guard service, has called the CBS newsroom "a tough place to work" where only the "savvy" survive. Appearing on Joe Scarborough's talk show on MSNBC Monday, Mapes suggested that Katie Couric is unlikely to remain a Survivor. "She's gone from being sort of an exuberant presence to someone who looks like they've been kidnapped and drugged and are making a hostage tape," she said. She dismissed the notion that Couric's low ratings have resulted from the public's unwillingness to accept a woman as news anchor, saying that the main problem is that Couric is "just not comfortable to watch."
