In papers filed in Manhattan Supreme Court, the former CBS Evening News anchor says his reliance on the network's false promises that it would defend him after making him a scapegoat for a controversial news report cost him several high-profile jobs - and some lower-profile ones as well.While he was once a hot property coveted by CNN to be its "face," the fallout from his report on President Bush's Air National Guard service resulted in him being turned away from even part-time jobs at CNN, ABC, NBC, Fox, HBO, the History Channel, A&E, Discovery and National Geographic channels, the filing says.
