Anderson Cooper’s daytime talk show is going through dramatic behind-the-scenes changes at the same time it was just sold for a second season. Exec producers Cathy Chermol and Lisa Morin, who joined “Anderson” in June, have stepped down. Terence Noonan has joined the show from “Dr. Oz” as an exec producer. Sources said Morin left for personal reasons, and Chermol left after Cooper disagreed with her handling of a Nov. 15 special on the Penn State scandal, called “State of Shame.” A source said Chermol instructed the audience not to hold back emotion. But Cooper took exception to the instructions. The source added while such a practice would be commonplace on a show like Cooper’s, the host disagreed with it. But a source inside the show said the departures were a natural evolution: “There’s nothing salacious. In [daytime TV] you are constantly making changes. It’s such a natural evolution.” A rep had no comment. Veteran Jim Murphy remains an exec producer along with Cooper.
