Michael Wolff, the author of a new book "Fire and Fury: Inside the Trump White House" about U.S. President Donald Trump's White House, says Trump has "creepy" knowledge about who around him is Jewish.

Tur, who followed Trump on the 2016 presidential campaign trail, asked Wolff about whether or not he believed Trump is an anti-Semite, racist and sexist. Wolff answered a flat out "yes" when asked if he believes Trump is sexist and racist.

The author also appeared on NBC's "Meet the Press" on Sunday and defended his portrayal of Trump in the book, along with his reporting methods.

"The book speaks for itself, read the book, see if you don't feel as if you are with me on a couch in the White House and see if you don't feel alarmed," Wolff said.

Wolff was granted unusually wide access to the White House during much of Trump's first year at the behest of former Trump strategist Steve Bannon, who advised the president during his first months in office and during his presidential campaign.

Wolff has said the book was based on White House access, conversations with Trump and interviews with senior staffers, including Bannon.

Its publication prompted Trump to write Saturday on Twitter that he is a "very stable genius." He dismissed Wolff as a "fraud" and called the book a "work of fiction".
