James Pogue's reporting for Vanity Fair has been one of the most-talked-about political articles of the year. Brian Stelter asks Pogue about the "dissident right;" its use of words like "regime;" and why it flies under the radar of much of the media. Pogue describes how he gained the trust of key sources like J.D. Vance and Blake Masters. He warns that "if we don't get government working again, on some level, somebody is going to come in and do something very authoritarian because our society is breaking down."
