The parents of a murdered Democratic National Committee staffer whose death fueled a right-wing conspiracy over DNC emails published by WikiLeaks during last year’s presidential election filed suit against Fox News late Tuesday, alleging the company’s publication of the initial story made them “collateral damage in a political war to which they are innocent bystanders.”

The suit, filed in the U.S. District Court for the Southern District of New York by Joel and Mary Rich, whose son, Seth, was murdered in July 2016, accuses Fox News reporter Malia Zimmerman and frequent guest and political operative Ed Butowsky of “intentionally exploit[ing] this tragedy—including through lies, misrepresentations and half-truths—with disregard for the obvious harm that their actions would cause Joel and Mary.”
