In his first public comments on the matter, President Trump told Axios that his niece, Mary Trump, is "not allowed" to write her forthcoming book about him because doing so would violate a nondisclosure agreement she signed.

Driving the news: "She's not allowed to write a book," Trump told me. "You know, when we settled with her and her brother, who I do have a good relationship with — she's got a brother, Fred, who I do have a good relationship with, but when we settled, she has a total ... signed a nondisclosure."

  • Trump said his niece's nondisclosure agreement with him was a "very powerful one. ... It covers everything."

Between the lines: Trump's comments to Axios confirm a Daily Beast story from last week, which broke the news of the NDA.

  • The Beast reported: "Mary Trump signed an NDA following a 2001 settlement after litigation disputing Fred Trump’s estate, according to people familiar with the matter. That NDA states she is not allowed to publish anything regarding the litigation or her relationship with Donald, Maryanne, and Robert."
  • "Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man" is slated to be published on July 28. Late on Monday night, following The Daily Beast's story, the publisher of Mary Trump's book, Simon & Schuster, posted the book on Amazon, where it quickly soared up the charts with pre-sale orders.
  • "In the book, Mary Trump is not only expected to discuss difficult internal family dynamics and offer revelations about a younger Donald Trump; she is also expected to out herself as a primary source behind a Pulitzer-winning New York Times investigation into her uncle's taxes," per The Daily Beast.

Trump suggested to Axios that he and some members of his family were blindsided by the news of the book.

  • "I have a brother, Robert, very good guy, and he's — he's very angry about it," the president said. "But she signed a nondisclosure agreement and she's obviously not honoring it if she writes a book. It's too bad."
  • "I have a good relationship with [Mary Trump's] brother. I actually had him — he was in here. He was sitting right in the seat where you are last week, unrelated to that. I didn't even know — maybe two weeks ago. I didn't even know about a book coming out until just the other day."

I asked the president about his niece's allegation that he "dismissed and derided" his father when he began to succumb to Alzheimer's.

  • "It's totally false; the opposite," Trump said. "Actually, the opposite. I always had a great relationship. I didn't know that she said that. That's a disgraceful thing to say."

Mary Trump did not respond to requests for comment. Simon & Schuster's director of publicity, Julia Prosser, declined to comment.

Mary Trump book: How she leaked Trump financials to NYT

Simon & Schuster

In her new memoir, President Trump's niece reveals how she leaked hordes of confidential Trump family financial documents to the New York Times in an effort to expose her uncle, whom she portrays as a dangerous sociopath.

Why it matters: Trump was furious when he found out recently that Mary Trump, a trained psychologist, would be publishing a tell-all memoir. And Trump's younger brother, Robert, tried and failed to block the publication of "Too Much and Never Enough: How My Family Created the World's Most Dangerous Man."
