The anonymous senior Trump Administration official who penned an op-ed last year describing the “resistance” operating inside the White House will publish a tell-all book in November.

The book, titled “A Warning,” will be released on Nov. 19 and the author will remain unnamed, according to publisher Twelve, an imprint of Grand Central Publishing/Hachette Book Group.

It is being promoted as “an unprecedented behind-the-scenes portrait of the Trump presidency” that goes beyond what was written in the Sept. 5, 2018, op-ed in the New York Times.

“Picking up from where those first words of warning left off, this explosive book offers a shocking, first-hand account of President Trump and his record,” a statement from the publisher said.

The author of “I Am Part of the Resistance Inside the Trump Administration” described Trump’s decision-making process as “half-baked, ill-informed and occasionally reckless.”

“The dilemma – which he does not fully grasp – is that many of the senior officials in his own administration are working diligently from within to frustrate parts of his agenda and his worst inclinations,” the person wrote in the piece. “I would know. I am one of them.”

Trump accused the writer of treason and ordered the Times to hand in “the GUTLESS anonymous person.”
