Tapper accused a "combative" Miller of wasting his viewer's time as the White House insider tried to redirect the conversation away from claims made about Trump in Michael Wolff's book Fire & Fury: Inside The Trump White House.
Miller called Tapper "condescending" and attempted to say that CNN has 24/7 negative coverage of Trump and the viewers deserved to hear three minutes of the truth.
Tapper told Miller during the interview that he was being "obsequious" and that he was performing for an "audience of one", referring to the president.
White House policy advisor Stephen Miller delivered a Golden Globes worthy performance for best actor in an insane drama of his own creation on Sunday.
Steven Bannon has been torpedoed by President Trump, his stakeholders in Breitbart News and conservative media, he is now on his knees pleading for mercy, his political career destroyed.
In fairly short order, Miller began to attack CNN in order to avoid Tapper's tough questioning, insisting that "it brings a lot of you guys a lot of joy" to report on the allegations in Wolff's book, "Fire and Fury". When the White House released its official transcript Tuesday afternoon, the president's line - "Yeah, I would like to do it" - was missing.
".And with respect to the Trump Tower meeting that [Bannon's] talking about [in Wolff's book], Bannon was not even there when any of this went down".
"If you want to take it that further step, I'll take the heat".
Both CNN and the White House declined to comment on the nature of Miller's departure.
Nikki Haley, the USA ambassador to the United Nations, said she visits the White House once a week, and "no one questions the stability of the president".
Miller's interview with Tapper was extremely contentious, and ended when Tapper chose to abandon the segment and move on to other subjects.
"I think I've wasted enough of my viewers' time", Tapper said.
"Not only do I think they help it, but I think in the toxic environment that you've created here and CNN and cable news, which is a real crisis of legitimacy for your network", Miller told Tapper. "Now I have to put up with a Fake Book, written by a totally discredited author", he tweeted.
