"But I think that given the extraordinary circumstances, the New York Times was ethically justified in publishing the piece - assuming, of course, that they know for certain who the author is and that he is a senior administration official, and that they have vetted the facts as well as they can". "[Donald Trump] has a clear governing vision for the country and his record of results is remarkable".
"Nearly 62 million people voted for President Donald J. Trump in 2016, earning him 306 Electoral College votes - versus 232 for his opponent".
A spokesman for Mr Pence said the vice-president does not write anonymous opinion columns.
Buzzfeed News reported that Pompeo, the U.S. Secretary of State, had denied writing the piece.
Trump went on a private hunt to discover the identity of the author, who characterized Trump as an amoral and temperamental threat to the nation surrounded by concerned senior staff and cabinet members diligently working in concert to check his worst impulses. "The @nytimes should be ashamed and so should the person who wrote the false, illogical, and gutless op-ed", Agen wrote on Twitter.
Trump describes the editorial as "gutless".
The anonymous author wrote in the Times that where Trump has had successes, they have come "despite - not because of - the president's leadership style, which is impetuous, adversarial, petty and ineffective".
Sanders also says the Times should apologize for publishing it. Implying there could eventually be a digital investigation into who authored the op-ed, one senior administration official said, "I hope they used a typewriter".
Trump on Wednesday was livid over a New York Times op-ed from an anonymous high-level official who claimed to be part of a secret White House resistance. "This is just another example of the liberal media's concerted effort to discredit the President", she said.
Trump lambasted The Times and the op-ed's author, whom he described as someone "who's failing and probably here for all the wrong reasons", during a speech at the White House on Wednesday. You are "not protecting this country", she said in a statement. "So we will do what we can to steer the administration in the right direction until - one way or another - it's over".
"President Trump is facing a test to his presidency unlike any faced by a modern American leader", said the author of op-ed titled "I am part of the resistance inside the Trump administration".
According to Buzzfeed, Pompeo said the anonymous op-ed was "sad" and said The New York Times should not "have chosen to take a disgruntled, deceptive bad actor's word for anything and put it in their newspaper".
Trump called Woodward's new work "fiction".
US Representative Mark Meadows of North Carolina, a congressional ally of Trump's, said he thinks the issue is "serious from a national security standpoint". Woodward's account also quotes Defense Secretary Jim Mattis as saying that Trump comprehends material at the level of "a fifth- or sixth-grader".
