Before things got contentious, Miller made his worst stumble when answering for Bannon's assertion that there was no way Trump didn't meet with the Russians who attended the June 2016 Trump Tower meeting. Trump dismissed the book as "full of lies" on Twitter and threatened Wolff with legal action after the book was published.
The original remark, published in Mr Wolff's book Fire and Fury: Inside the Trump White House, and not disputed by Mr Bannon, appeared to take aim at all three Trump campaign officials in the room, including Donald Jr.
"I'm sure he's watching this on TV and is very happy that you said that", Tapper said about Trump, prompting Miller to call Tapper "condescending". "You're being obsequious, you're being a factotum in order to please [Trump]". He urged his followers to "watch the hatred and unfairness of this CNN flunky!"
As the interview progressed, Miller talked at length about experiences on the campaign trail, his perceptions of the president, CNN's negative coverage of the president and Tapper's inability to relate to working class people.
"It makes the president's job so much easier", says Houck, "to rally his supporters ahead of the midterm election". "But what I can tell you unequivocally is that the allegations and insinuations in this book, which are - which are a pure work of fiction, are nothing but a pile of trash through and through".
Wolff said that he went to other sources and said, "The president likes this idea, and everyone would say, 'OK, great'". He pressed the case again yesterday as he prepared to depart Camp David for the White House.
"You should be ashamed of yourself", an angry Miller replied. In fact, he has never been there.
"I see sections of the book where events I participated in are described, and I have 1st-hand knowledge, as they're described, they're completely and utterly fraudulent".
He said Trump's immigration reform is based on that the country should be as loyal to Americans as Americans are loyal to the USA - citizens who obey the laws, follow the rules, pay their taxes, and show up and vote.
The two then went on to discuss Trump's letter firing former FBI Director James Comey before turning to Trump's mental fitness for the presidency.
Wolff's book landed in bookstores last Friday and is a best seller.
