Sumner Redstone‘s ugly family feud with his daughter Shari just got uglier. Redstone faxed Forbes a letter insulting Shari (the vice chairwoman of both Viacom and CBS) and describing her as someone who “ignores the cardinal rule of good governance.” Also, he reminds the magazine that he built up Viacom with “little or no contribution” on his children’s part. Smooth. Forbes described Sumner and Shari’s feud over Viacom’s future; Shari’s spokeswoman Nancy Sterling states it “is unfortunate that Sumner has chosen to publicize what Shari had hoped would remain a private family matter.”
Currently, Sumner is attempting to position Viacom CEO Philippe Dauman as his designated successor.
