The suit, filed in New York’s Dutchess County, alleges NYT journalists “engaged in an insidious plot to obtain confidential and highly-sensitive records” and that they “convinced” Mary Trump to “smuggle records out of her attorney’s office and turn them over to The Times.”

Of note: Trump challenged the release of a book by Mary Trump on him last year, telling Axios’ Jonathan Swan she was “not allowed” to write it due to a non-disclosure agreement she signed. A judge ruled publisher Simon & Schuster did not seem bound by this.

Trump alleges in his suit against the NYT and his niece that she “committed a material breach of the Settlement Agreement by disclosing, assisting and/or providing confidential information to The Times.”
