Conservative talk show host Glenn Beck slammed Donald Trump’s supporters Wednesday on his radio show as “vile” and likened them to Nazis – while accusing Breitbart Chairman Stephen Bannon of doing Trump’s bidding, comparing him to Nazi propagandist Joseph Goebbels.

The conservative radio personality and former Fox News host lit into Trump and Bannon following an incident on the sidelines of Tuesday’s Nevada caucuses, in which Trump visited a caucus site where Beck was campaigning for Texas Sen. Ted Cruz.

On his show, Beck accused Trump of dividing the country and “grooming brownshirts,” while describing many of the Trump supporters he encountered Tuesday as “beyond recognition as anything I’ve ever seen — rude, vile, nasty.”

But he reserved his most fiery comments for Bannon, claiming his Breitbart news blog site is promoting Trump’s “lies.”  

“I’m telling you that I believe that Bannon thinks he’s either going to be the chief of staff or he’s going to be the next Roger Ailes. And let me tell you something, Bannon whatever your first name is. Um, you’re not going to be the next Roger Ailes. There is not going to be another Roger Ailes,” Beck said, referring to the Fox News chairman.

He continued: “Roger Ailes didn’t answer to anybody. He certainly didn’t take orders from a real estate developer. … By taking orders from a political candidate and reworking your entire site to promote the lies of a specific candidate without any kind of truth behind these things ... If that is what your idea of being Roger Ailes is, you are so sadly mistaken. That doesn’t make you Roger Ailes. That makes you Goebbels.”

Reached for comment, a Breitbart spokesman jokingly referenced Beck’s call to fast for Cruz, saying:

"Since Glenn had been fasting, we assume he was simply 'hangry.' Either that or this is another example of Beck trying to carry water for the Ailes-Murdoch-Fox News establishment in their anybody-but-Trump crusade." 

The conservative news blog site’s primary financial backer is Robert Mercer, a billionaire supporter of various political causes.

Beck specifically had objected Wednesday to the way a Breitbart article described his comments regarding Trump’s caucus site appearance. The host, though, stood by his criticism of Trump supporters. 

Trump won the Nevada caucuses on Tuesday by a double-digit margin. Beck’s favored candidate, Cruz, came in third.
