Some of the highest-ranking members of President Donald Trump’s administration on Thursday distanced themselves from an anonymous New York Times op-ed that outlined an internal “resistance” movement focused on thwarting what the author called Trump’s “misguided impulses.”

The piece is credited only to “a senior official in the Trump administration,” and it kicked off a wild guessing game inside the White House and out about the author’s identity, prompting officials from Defense Secretary Jim Mattis to budget chief Mick Mulvaney who have denied either publicly or in response to POLITICO inquiries that they were responsible for the op-ed.
