The result was that the White House appeared to be badly wrong-footed on Tuesday as the first excerpts of the book emerged. He's so detail-oriented in this area that reportedly he's chose to film some recent statements in the Rose Garden because he believes the lighting outdoors makes him look better.
Even the biggest controversies feel like old news.
What does the chaos in the White House mean for India?
"It felt like we were walking along the edge of the cliff perpetually", Mr Porter is quoted as saying. Both these reached the top Times bestseller spot, as well.
It would be hard to find a journalist with greater credentials. The book, due for release on September 11, is already causing a political 9/11, even as the President and the Woodward-backing liberal press in the United States are locked in a struggle to establish who is more credible.
But even the president's deputy press secretary wouldn't have been able to make that interview happen, because Trump says he never talks to the man. "Let's go in." Mattis assured Trump he would get right on it but then told a senior aide they'd do nothing of the kind, Woodward wrote. I'll never be a staffer.
Trump's current chief of staff, John Kelly, also is quoted calling Trump an "idiot" and "unhinged" and describes his White House role as the worst job he ever had.
On the call, Trump sounded anxious, repeating his refrain that it would be a "bad" book for him, and that Woodward did not understand just how successful he had been in office. That's hard to completely refute.
Trump's former lawyer in the Russian Federation probe, John Dowd, is also said to have doubted Trump's ability to avoid perjuring himself should he sit down with special counsel Robert Mueller. "I've killed people for a living". Trump apparently never realized the letter had disappeared. Many seem to have sat for hours. Subjects and critics of Woodward's books over the years have complained about his zealous approach to narrative reconstructions and some of the details in his reporting, while largely failing to undermine the broader thrusts of a body of work built upon heaps of in-depth, recorded interviews and ample documentation. Trump critics are quick to believe the worst. "I think the president's probably got a lot of respect for the South, I hope so".
But in general, Trump is not known for assiduous adherence to the facts, given the many fact-checker tabulations of his misstatements.
Woodward isn't interested in analytical writing, theorizing, or other abstract aspects of journalism, says Greenberg.
"I'm not gonna get into name calling because I don't think you should be allowed to call names - including the president", Isakson added. "But you know, they - it was rejected".
Former George W. Bush press secretary Ari Fleischer defended Woodward's methodology. All had some complaints about particular incidents or depictions. Will anyone else quit?
"I was criticized in one magazine, where the writer was retarded", Trump said at the time.
