Two sources told the news website that Miller refused polite requests to leave after taping his interview segment, forcing security to be called to escort him out.
CNN declined to comment to Business Insider.
In the interview, Miller insulted CNN’s journalism and refused to answer Tapper’s questions about President Trump’s knowledge of interactions with Russians during the presidential campaign.
In the end, Tapper eventually shut the conversation short, saying, “I think I’ve wasted enough of our viewers’ time.”
Miller also said that CNN has “24 hours of negative anti-Trump hysterical coverage” and “spectacularly embarrassing false reporting.”
He then asked for three minutes to tell “the truth about the Donald Trump I know.” Tapper replied that he wouldn’t allow that because “it’s my show and I don’t want to do that.”
