Staffers at the five major television networks are grappling with what role their organizations may have played in amplifying Donald Trump’s successful campaign of insults, generalizations about minority groups, and at times flat lies.

Conversations with more than a dozen reporters, producers, and executives across the major networks reveal internal tensions about the wall-to-wall coverage Trump has received and the degree to which the Republican frontrunner has — or hasn’t — been challenged on their air.

Two network sources also confirmed the unprecedented control the television networks have surrendered to Trump in a series of private negotiations, allowing him to dictate specific details about placement of cameras at his event, to ensure coverage consists primarily of a single shot of his face.

Network officials say the ratings have born out commercial incentives to devote their campaign coverage to largely unfiltered streams of Trump talking. CBS CEO Les Moonves quipped that Trump “may not be good for America, but it’s damn good for CBS, that’s all I got to say.”
