An interview between CNN anchor Anderson Cooper and White House deputy assistant Sebastian Gorka took a sharp turn Wednesday amid the ever-expanding controversies surrounding the White House.

The interview initially focused on the 2016 meeting between Donald Trump Jr. and a Kremlin-linked Russian lawyer that has dominated headlines since Saturday. A Politico report on Tuesday said White House aides felt “helpless” as the scandal took on a life of its own. But Gorka disputed such a characterization.

“It’s laughable, your chyron talked about a ‘crisis,'” Gorka told Cooper, responding to a suggestion that the White House was in turmoil. He added: “I actually work in the West Wing, I work in the White House — it is absolutely nothing of the kind. The president is a steam locomotive that can’t be stopped. It’s just fake news.

“I’m sad to see CNN fall to this,” Gorka continued. “I know you want salacious and sensational coverage for your ratings so your corporate sponsors and owners will have more money, but that’s not media, that’s not reportage. It’s just fake news.”

Cooper responded by saying he was “just going to ignore the insults” and didn’t believe Gorka’s comments were going to be helpful to the conversation.
