Former TV news anchor Dan Rather sued CBS Chief Executive Leslie Moonves and former CBS News President Andrew Heyward on Monday in a bid to have them reinstated as defendants in his $70 million lawsuit against the network. In a lawsuit filed in New York State Supreme Court, Rather accused the two men of fraud relating to his claim that CBS made him a scapegoat in a scandal over a 2004 report on then-President George W. Bush's military record.
