Vice President Mike Pence's office is denying that he is the senior administration official behind an extraordinary, anonymous opinion essay describing a "resistance" against President Trump.
The New York Times' publication set off a wave of intense speculation about the author's identity.
Observers seize on the essayist's use of the word "lodestar," which Pence often uses in his speeches and statements, as possible evidence the op-ed came from the vice president or among his top staff.
