Earlier this year, when Steve Bannon was still running the right-wing website Breitbart and transforming it into an arm of Donald Trump’s presidential campaign, Glenn Beck warned that Bannon was a “horrible, despicable human being,” likening him to Adolf Hitler’s propagandist Joseph Goebbels. A few months later, when Trump tapped Bannon to serve as a key adviser to his campaign, Beck raised the alarm again, declaring that Bannon was “quite possibly the most dangerous guy in all of American politics.”

Now that Trump has announced that Bannon will serve chief strategist and senior adviser in the White House, Beck issued another warning on his radio show today.

Bannon wants to burn the entire system to the ground, Beck said. “He’s a nightmare and he’s the chief adviser to the president of the United States now.”

“Bannon has a clear tie to white nationalists,” he stated. “Clear tie. He’s built Breitbart as a platform for the alt-right. He is on record saying that. He’s on record defining the alt-right. He knows what it is. He is a guy who wants to tear this system down and replace it with a new system. He is a frightening … no, he is a terrifying man. A terrifying man.”
