The brother of slain DNC staffer Seth Rich on Tuesday penned a letter to Fox News host Sean Hannity’s producer, pleading with him to stop giving airtime to unfounded conspiracy theories around his brother’s death. “Think about how you would feel losing a son or brother. And while dealing with this, you had baseless accusations of your lost family member being part of a vast conspiracy,” Aaron Rich wrote in the letter to Hannity executive producer Porter Berry. “It is a travesty that you would prompt false conspiracy theories and other people's agendas rather than work with the family to learn the truth.” Rich was shot to death last year and conspiracy theories alleging he was murdered by the DNC for his alleged connections to WikiLeaks have persisted for months, eventually making their way to Hannity’s air last week. The Daily Beast reported on Monday that many Fox News staffers are “embarrassed” and “disturbed” by the primetime star’s incessant promotion of unfounded conspiracy theories, despite the family’s plea for him and others to stop.
