Charles Krauthammer said White House Chief Strategist Stephen Bannon was "Scaramucci-ed" after he called a reporter to discuss politics.
Reporter Robert Kuttner with the American Prospect later published quotes from their conversation.
Bannon sounded off on "ethno-nationalism" as seen in Charlottesville, calling the rioters "losers" and a "fringe element."
Bannon also appeared to differ from the White House line on how to handle North Korea.
Krauthammer said he "totally contradicted" Trump's "fire and fury" threat by saying there is no real solution to Pyongyang's aggression.
"This [conversation] was completely unnecessary," Krauthammer said, adding that Bannon had to know that he was being recorded.
"I think Bannon just got Scaramuccied," he said, referring to how former White House Communications Director Anthony Scaramucci's discussion with reporter Ryan Lizza was published.
Scaramucci was later fired by Trump after he badmouthed Bannon and former Chief of Staff Reince Priebus.
Judge Andrew Napolitano added that Bannon could've been trying to make himself the "center of attention" after "the worst week of [Trump's] presidency."
