Veteran ABC newsman Sam Donaldson has told the Washington Post that he is leaving the network after 41 years. "Some people leave the business bitter, feeling they've been cast out, or they hang on too long," he told the newspaper. "And I don't ever want to get in that position." In fact, he may already have been placed in that position. The former White House correspondent and co-host of This Week and Primetime Live more recently has been relegated to co-hosting Politics Live on ABC's website -- "talking to an audience of dozens," as he puts it. Donaldson said that he did not ask for a contract renewal. "If they were going to push me, at least I jumped before they did."
