What was the nature of Tony Schwartz's working relationship with Donald Trump during the book's writing?

1. A working relationship built on access and observation

Tony Schwartz’s account of the writing process centers on immersion: he “shadowed” Trump in offices, residences and meetings for many months (about 18 months is often cited) and collected interviews and observations that he says formed the book’s text ^{[1] [2] [4]}. Schwartz framed his role as the person who synthesized Trump’s voice and behavior into a marketable narrative, not merely a stenographer, which is consistent with typical ghostwriter practices described in the reporting ^{[2] [4]}.

2. Who wrote which words: competing claims

Schwartz has repeatedly said that Trump “wrote none of the book” and that he (Schwartz) is responsible for the text, while Trump has given conflicting statements—at times praising Schwartz as “very good” and at other times insisting “I wrote the book” ^{[1] [5] [6]}. The book was published as “Donald Trump with Tony Schwartz,” and Howard Kaminsky, the Random House head at the time, said Trump didn’t write material for the publisher, which supports Schwartz’s claim that Trump did not provide the manuscript directly ^[6].

3. The practical dynamics: short interviews, long shadowing

Schwartz told interviewers that Trump had a short attention span in formal interviews—reportedly unwilling to sit for long, answering only briefly—so much of Schwartz’s material came from prolonged observation and numerous short interactions rather than long scripted writing sessions with Trump ^{[4] [2]}. That pattern explains why Schwartz emphasizes his own active role in producing the prose and shaping the narrative ^{[4] [2]}.

4. Money, credit and public visibility shaped the relationship

Schwartz was credited as co-author and reportedly received half of the advance and royalties, reflecting an acknowledged co-authorship arrangement even as public statements later diverged ^[2]. The joint byline and financial split indicate an official arrangement that recognized Schwartz’s substantial contribution, though later public disputes over how much each man “wrote” created contested narratives ^{[2] [6]}.

5. Evolving relationship: from collaboration to public break

After the book’s success, Schwartz and Trump stepped away from close contact; Schwartz later became an outspoken critic and publicly regretted helping craft Trump’s image, calling it his “greatest regret” and saying the experience haunted him—an arc that turned a one-time working partnership into a public feud ^{[1] [3] [2]}. Trump’s responses included personal attacks and threats of legal action, signaling a personal and public rupture between the men ^[1].

6. What the sources agree on — and where limits remain

Sources consistently show Schwartz played an intensive, hands-on role—interviewing and observing Trump and writing the book’s prose—while Trump has given contradictory accounts of authorship ^{[1] [5] [6]}. Available sources do not mention a verbatim manuscript exchange where Trump produced full draft chapters himself, and the original publisher’s statement supports the view that Schwartz supplied the text ^[6]. However, the exact degree to which Trump contributed phrasing, anecdotes or approvals at various stages is contested in public statements ^{[5] [6]}.

7. Why this dispute matters beyond credits

The disagreement over who “wrote” The Art of the Deal is not only about literary credit or money; Schwartz argues he helped create a public persona that later had political consequences, which is why he later condemned the work and sought to correct public understanding ^{[3] [2]}. Trump, conversely, has repeatedly invoked the book as a core element of his personal brand and has resisted accounts that minimize his creative role ^{[6] [5]}.

8. Bottom line for readers

If you accept Schwartz’s account, the working relationship was one of deep reporter-ghostwriter immersion where Schwartz produced most or all of the prose from extended observation; if you accept Trump’s later denials, the relationship is recast as one where Trump claims primary authorship despite the publisher’s recollection and Schwartz’s repeated statements ^{[1] [6] [4]}. Readers should weigh the contemporaneous publisher statement and Schwartz’s detailed interviews against Trump’s shifting recollections when forming their judgment ^{[6] [5]}.
