"The Deep State and the Left, and their vehicle, the Fake News Media, are going insane - & they don't know what to do", he tweeted on Thursday morning. Members of his cabinet rushed to deny authorship in an unedifying spectacle reflecting the depth of suspicion gripping the Trump administration.
Vice President Mike Pence, Secretary of State Mike Pompeo, HUD Secretary Ben Carson, Attorney General Jeff Sessions and other cabinet members have also denied being the author.

Trump called Woodward's new work "fiction".
The opinion piece in The New York Times is similar to parts of a new book about Trump by reporter Bob Woodward.
The Times acknowledged the "rare step" of publishing an anonymous editorial but said the official's job would be jeopardized if they were identified.
