The Department of Justice is seeking information that could expose the current or former Trump administration official who is responsible for the anti-Trump op-ed and the upcoming anti-Trump book.

According to The Daily Caller:

The Justice Department is asking a publishing company for information that could identify a senior Trump administration official who blasted President Donald Trump in an anonymous New York Times op-ed last year, according to a letter released on Monday.

Joseph Hunt, the assistant attorney general for the civil division, sent the letter, published by the Times, to Hachette Book Group, and Javelin, the author’s literary agency. Hunt asks in the letter whether the administration official signed a non-disclosure agreement before joining the government, and whether they had access to classified information.

The official promises to provide “an unprecedented behind-the-scenes portrait of the Trump presidency” in the book, “A Warning,” which is scheduled for release on Nov. 19. The book is a continuation of the author’s op-ed, entitled “I Am Part of the Resistance Inside the Trump Administration.”

…

“If the author is, in fact, a current or former ‘senior official’ in the Trump administration, publication of the book may violate that official’s legal obligations under one or more nondisclosure agreements,” Hunt wrote in the letter.

The identity of the official isn’t specifically asked for but the identity could be determined in the information that the department has asked for.
