Security reportedly had to escort President Donald Trump's senior policy adviser Stephen Miller from the CNN studios on Jan. 7 (video below).
After Miller criticized the news network's credibility on the show "State of the Union," anchor Jake Tapper cut Miller's interview short, reports CBS News.
"I know that it brings a lot of you guys a lot of joy to trying to stick the knife in," Miller said of the network while defending Trump against claims made in journalist Michael Wolff's book, "Fire and Fury: Inside the Trump White House."
Tapper then accused Miller of refusing to answer his questions so he could earn the president's approval. Tapper said Miller was being "obsequious."
"I think I've wasted enough of my viewers' time," the CNN anchor said before cutting off Miller, Mediaite reports. "Thank you."
But the adviser reportedly chose to ignore Tapper's cue that the interview was over and refused to leave the set.
"The segment was over and Mr. Miller was politely asked to leave the set multiple times," a CNN source told CBS News. "After refusing to leave, he was escorted out by security."
Miller appeared on the show to defend Trump against the charges made in Wolff's book, but the interview turned combative.
The Trump adviser insisted the book was "nothing but a pile of trash through and through," adding it was "tragic and unfortunate" that former Trump strategist Steve Bannon made such untruthful "grotesque comments" to Wolff.
"Steve Bannon's eloquence in that description notwithstanding, it's tragic and unfortunate that Steve would make these grotesque comments, so out of touch with reality and obviously so vindictive," Miller said. "And the whole White House staff is deeply disappointed in his comments, which were grotesque," he said, using the adjective again.
"It reads like an angry, vindictive person spouting off to a highly discreditable author," Miller added of the book.
When Tapper asked if Miller had any first-hand knowledge of Trump meeting the Russians who visited his Manhattan office in Trump Tower in June 2016, Miller grew combative.
"I have no knowledge of anything to do with that meeting," he said when pressed about the issue a second time, before turning the conversation into an attack on CNN.
Miller's interview and the eventual conflict that ensued drew praise from the president.
"Jake Tapper of Fake News CNN just got destroyed in his interview with Stephen Miller of the Trump Administration," Trump wrote on Twitter. "Watch the hatred and unfairness of this CNN flunky!"
