Sebastian Gorka: I was told to cooperate with Michael Wolff

Former White House aide Sebastian Gorka slammed Michael Wolff's new book, "Fire and Fury," in an op-ed for the Hill, and he revealed that he "had been told to also speak to him for his book."

Why it matters: Gorka's comment seems to confirm Wolff's claims that he had access to White House staffers while reporting for the book, though Gorka did not make clear who told him to cooperate with the author.
