"Don't you think people look through the fact that you can write a sensational, nonsense book, CNN will definitely have you on there because they love to trash the president," Trump said, responding to Fox and Friends host Steve Doocy, who asked if the book detailed "chaos" in the White House. "It will mean you sell three extra books, you make three extra shekels."

"Is that really where we are? I think people read through this," he said.

Woodward's book, "Fear: Trump in the White House," which details dysfunction in the White House and broader administration, was released Tuesday.

The Watergate journalist has responded by pointing to the hours of interviews with dozens of sources he conducted for the book. On Tuesday, he said one source told him it was 100 percent accurate.

The president called the book a "joke" in a tweet Monday morning, and threatened to counter the release of Woodward's reporting with "the real book" of his own.

"The Woodward book is a Joke - just another assault against me, in a barrage of assaults, using now disproven unnamed and anonymous sources," he tweeted. "Many have already come forward to say the quotes by them, like the book, are fiction. Dems can’t stand losing. I’ll write the real book!

The use of the term "shekels" by Eric Trump is likely to draw scrutiny given its use by white nationalists to describe money they say has been tainted by Jewish influence.
