Miller also described the former chief strategist's role was "greatly exaggerated" and twice called Trump a "political genius".
The White House has been on the defensive since excerpts of the book were published last week with the president and his aides scrambling to discredit both its portrayal of Trump and the author's methods. The amendment allows for the removal of a president if the vice president and a majority of the cabinet deem him physically or mentally unable to perform his duties.
Mr Wolff says his book is based on more than 200 interviews with the President and his senior staff over an 18-month period.
In the book, Bannon predicted that the special counsel investigating possible collusion between the Trump campaign and Russian Federation would "crack" the younger Trump "like an egg on national TV".
"The President's tweets absolutely reaffirm the plainspoken truth: A self-made billionaire revolutionized reality TV and tapped into something magical that's happening in the hearts of this country", Miller said.

His wife told officials a similar version and said that they had called the flight attendants to try to change seats. She told authorities the man next to her had his fingers inside her trousers , and that he stopped when she woke up.
"I've had to put up with the Fake News from the first day I announced that I would be running for President".
"Miller also lamented Steve Bannon for making "grotesque comments" in the book, ones he said are "so out of touch with reality" and vindictive". Ronald Reagan had the same problem and handled it well.
British Prime Minister Theresa May dismissed concerns about Mr Trump's mental state after the book's publication, saying the President would still be visiting the United Kingdom in the future.
"We urge that those around him, and our elected representatives in general, take urgent steps to restrain his behaviour and head off the potential nuclear catastrophe that endangers not only Korea and the United States but all of humankind", they wrote. Bannon referred to a 2016 meeting between Donald Trump Jr and a Russian Federation lawyer at Trump Tower as "treasonous" and suggested that it was highly likely that Trump Jr told his father about the meeting. The interview became so contentious that Tapper cut the interview short and said Miller was wasting his viewers' time.
Asked whether the president was aware of the meeting at the time, Miller said Bannon was not present and therefore "is not even a remotely credible source on any of it".
What began as a routine interview on his show, State of the Union, quickly turned into a battle to be heard, with Tapper trying to fit in his questions as Miller shouted over him with increasing anger. 'Watch the hatred and unfairness of this CNN flunky!' The president later said on Twitter that Tapper "just got destroyed in his interview" with Miller.
