Gunman in Virginia TV shooting had history of workplace issues

The gunman in the shooting deaths of two television journalists in Virginia was a veteran anchorman with a history of workplace grievances who had previously sued a Florida station alleging discrimination because he was black.

While authorities said they had not determined a motive, perceived racism appeared to be a factor in the shootings, according to posts on social media attributed to the shooter and a fax that ABC News said had been sent by the gunman.
