WATCH: Ex-Trump adviser pouts like a toddler after C-SPAN viewer calls him ‘treasonous’ on air

Former White House aide Sebastian Gorka went on C-SPAN's "Washington Journal" on Tuesday in which he encountered an angry Democratic caller who accused him of treason.

During the episode of the C-SPAN show, the caller began by thanking Gorka for making an appearance -- and then he proceeded to viciously attack the Trump administration.

"I just really look forward to when you and Corey Lewandowski, David Bossie and Don Jr., Jared Kushner, all of you are exposed for the treasonous b*tches that you are," the caller said.

C-SPAN promptly cut off the caller and the host apologized to Gorka for being subjected to a profanity-laced tirade.

Gorka, however, said that he wanted to comment about the nasty treatment he had just received.

"Why is there such hatred out there -- it's just un-American," said Gorka, who was not born in the United States. "This is a duly elected president! People need to get over the fact that we have a republic... This level of hatred -- not good for the health of the republic."
