Judge lifts block on Trump book publisher, but upholds order on his niece

What they're saying: "While Ms. Trump unquestionably possesses the same First Amendment expressive rights belonging to all Americans, she also possesses the right to enter into contracts, including the right to contract away her First Amendment rights,” the judge said.

• "Unlike Ms. Trump, Simon & Schuster has not agreed to surrender or relinquish any of its First Amendment rights."

The big picture: The president's younger brother Robert Trump filed a lawsuit against their niece, who's the daughter of their deceased elder brother Fred Trump Jr., over the tell-all book.

• The president told Axios' Jonathan Swan last month that Mary Trump was "not allowed to write a book" because of the non-disclosure agreement she signed.

• A New York judge issued an injunction temporarily blocking publication of the memoir on Tuesday.
