Comcast executives sent a letter to their employees on Friday, September 12, urging them to be respectful in their coverage of Charlie Kirk. The letter comes after MSNBC contributor Matthew Dowd was fired for comments he made on-air shortly after the conservative activist's death. Kirk died on Wednesday at age 31 after he was shot while speaking at an event at Utah Valley University. Authorities arrested 22-year-old Tyler Robinson on Friday in connection with the shooting.
