CNN's Jake Tapper, who was conducting the interview with White House Senior Adviser Stephen Miller, cut the conversation off after 12 and a half minutes, telling Miller he was spewing rhetoric exclusively to gain approval from the President.
"I would have been delighted to have written a contrarian account here: Donald Trump, this unexpected President is actually going to succeed", Mr Wolff said.
When Tapper asked questions, Miller often attacked CNN as running "24/7 with salacious coverage" of the Trump administration.
Mr. Tapper then turned to the camera, even as Mr. Miller was still speaking, and cut to a commercial.
The newsman also got into a tussle with Miller over who hired him, suggesting it was Bannon who helped bring the young aide on board. He also lauded Trump as a "political genius".
He said his description of the "treasonous" and "unpatriotic" meeting was aimed at former Trump campaign manager Paul Manafort, not Trump's son.
In a tense interview, CNN anchor Jake Tapper concluded by telling Miller that "there is one viewer that you care about right now", referring to Trump. "Watch the hatred and unfairness of this CNN flunky!" It was fair for Trump to describe himself as a "genius" because it "happens to be a true statement", Miller said.
"I regret that my delay in responding to the inaccurate reporting regarding Don Jr has diverted attention from the president's historical accomplishments in the first year of his presidency", Bannon said.
Trump also tweeted that throughout his life, "my two greatest assets have been mental stability and being, like, really smart".
Mr Wolff says his book is based on more than 200 interviews with the President and his senior staff over an 18-month period. "The president's tweets absolutely reaffirm the plain spoken truth: self made billionaire who revolutionized reality TV, and tapped into something magical that's happening in the hearts of this country".
Miller tried to protest, but Tapper quickly said, 'Thank you Stephen.' The camera panned away from the White House aide as Tapper started reading from the teleprompter, readying his audience the next segment. "You're being obsequious, you're being a factotum in order to please [Trump]".
