NEW YORK -- Former CBS anchor Dan Rather has filed a $70 million lawsuit against the network.

Rather alleges that CBS made him a "scapegoat" for a discredited story about President Bush's National Guard service.

The suit also names CBS' former corporate parent, Viacom, and three of Rather's former bosses.

Rather's complaint cites what it calls "CBS' intentional mishandling" of the aftermath of the story.

The lawsuit was filed in State Supreme Court in Manhattan.

It also names CBS President and CEO Leslie Moonves, Viacom chairman Sumner Redstone, and Andrew Heyward, former president of CBS News.

Rather is seeking $20 million in compensatory damages and $50 million in punitive damages.
