Simon and Schuster has moved up the publication date for Too Much and Never Enough, the forthcoming tell-all memoir from President Trump’s niece, Mary Trump, the New York Times reports.

The book is now scheduled for publication on July 14. It was originally slated to hit bookstore shelves on July 28.

The publisher cited high demand as the reason for the publication date change, but it’s likely that a lawsuit by President Trump’s brother, Robert Trump, was a factor in the decision. Robert Trump sued his niece to stop publication of the book, which he says violates a nondisclosure agreement that Mary Trump had signed.

Last week, a judge ruled that the book could indeed be published.

The New York Times and the Washington Post both published highlights from the book on Tuesday. The Times report says that Mary Trump’s book claims that President Trump hired someone to take his SAT exam for him, and that his sister, Maryanne Trump Barry, thinks of him as “a clown.”

The report in the Post says that President Trump’s father “destroyed” his son by impairing “ability to develop and experience the entire spectrum of human emotion.

“By limiting Donald’s access to his own feelings and rendering many of them unacceptable, Fred perverted his son’s perception of the world and damaged his ability to live in it,” Mary Trump writes.

As of Tuesday afternoon, Too Much and Never Enough was the No. 1 bestselling book on the websites of Amazon and Barnes Noble.
