A judge has issued an order temporarily blocking the publication of Mary Trump’s tell-all book about her family, including her uncle, President Trump, the Washington Post reports.

The order comes just days after another judge declined to stop the book from being published, saying his court lacked jurisdiction in a lawsuit filed by President Trump’s brother, Robert Trump, who contended that Mary Trump’s book violated a nondisclosure agreement she had signed.

Judge Hal B. Greenwald ruled that Mary Trump’s book, Too Much and Never Enough: How My Family Created the World's Most Dangerous Man, cannot be published until the two parties can present arguments in the suit.

The book’s publisher, Simon and Schuster, said it will appeal the ruling, as did Mary Trump’s lawyer, Theodore Boutrous Jr., who called the judge’s order “a prior restraint on core political speech that flatly violates the First Amendment.”

The Daily Beast reported that Simon and Schuster said they didn’t know that Mary Trump had signed a nondisclosure agreement before publishing the book, and according to Forbes, the publisher has already shipped thousands of copies of the book, presumably to newsrooms and booksellers.

Too Much and Never Enough is currently slated for publication on July 28. As of Wednesday afternoon, it was the No. 1 bestselling book on Amazon.
