Two of media mogul Sumner Redstone’s longtime colleagues were dismissed as trustees for the trust that manages his holdings in Viacom Inc. and CBS Corp. over the weekend, The Wall Street Journal reports. Viacom Chief Executive Philippe Dauman and Director George Abrams claim Redstone, who has recently been embroiled in a legal fight over his mental capacity, would never have made this decision and is being manipulated by his daughter Shari Redstone who they allege is angling for control of the companies.
