Author Michael Wolff on Saturday sparred with CNN host Michael Smerconish over his new expose on the Trump administration, telling the host to just "read my book."

Smerconish questioned Wolff's reporting in "Fire and Fury: Inside the Trump White House," telling the author that it "begs interesting questions as to what grounds you were able to pull up that sofa in the West Wing."

In the 18 months during which Wolff said he held over 200 interviews with administration and Trump campaign officials, he has said he had "something like a semi-permanent seat on a couch in the West Wing."

"It's just a book, I've written a book, you either like it or you don't like it, so far it quite seems that many ... people like it and it speaks to them," Wolff said, rebuffing questions over his reporting methods.

"I just find it unusual you get the final word," Smerconish said, addressing Wolff's petitions to end the interview. "You can both enjoy the book and question some of its content."

The longtime media reporter's book has drawn criticism from journalists over what some have said are factual errors or misquoted lines from interviewees.
