I think that a congressional investigation of CBS is a terrible idea, and I’m surprised Chris Cox is proposing one. CBS right now lacks defenders. An official investigation will cause a lot of media outlets to spring to the network’s defense, citing First Amendment concerns. Whether or not those concerns are justified, there’s no reason for Republicans to raise them in the first place. Besides, right now the story is about CBS vs. the truth. Why would Republicans want to make it Republicans vs. CBS?
