"I would say Jeff should be investigating who the author of that piece is because I really believe it is national security", Trump told reporters travelling with him on Air Force One on Friday. "I would say Jeff [Sessions] should be investigating the author because it's national security".
The op-ed, titled "I Am Part of the Resistance Inside the Trump Administration", appeared on the Times' opinion page Wednesday and was written by an anonymous "senior official in the Trump administration".
"It may be cold comfort in this chaotic era, but Americans should know that there are adults in the room", the anonymous official wrote in the op-ed.
The op-ed claims that Cabinet officials discussed removing Trump from the presidency early on in his administration by invoking the 25th Amendment, but decided against such a move in order to avoid a "constitutional crisis". And it's far from clear that the vivid portraits of erratic presidential behavior described by Woodward and the op-ed writer would breach national security.
He told Fox News: "What they've done is virtually, you know, it's treason, you could call it a lot of things". Even liberals that hate me say: "that's awful what they did".
"I could think of four or five, mostly people that either I don't like or don't respect", he said.
Woodward describes Trump regularly insulting key members of his own team, who are in turn contemptuous of the president.

At 3:12 p.m. (1912 GMT), the Canadian dollar was trading 0.3 per cent higher at $1.3139 to the greenback, or 76.11 USA cents. But on the sidelines, President Trump and Prime Minister Justin Trudeau have dug into seemingly irreconcilable positions.
"We have somebody in what I call the failing New York Times that's talking about he's part of the resistance inside the Trump administration".
Trump attacked the book as a "scam", and suggested hardening the country's "pathetic" libel legislation.
Since the editorial was published, there have been several denials by many of Trump's senior officials with regards to who wrote it, but speculations are rife that Vice President Mike Pence may have authored the editorial.
The essay has enraged Trump and touched off a furious search inside the administration for its author.
"With nothing but positive news about the economy and the job market, all of their fears have come true", Borelli told The Post.
The official said there were a number of USA officials who were part of an "quiet resistance" inside the administration who was "working diligently from within to frustrate parts of his agenda and his worst inclinations". Even in an administration defined by its seeming unending capability to amaze and disrupt standard procedures of governance, the idea that there is an active effort among top aides to marginalize Trump stands out.
