President Trump ripped Bob Woodward's book on Twitter Monday, calling it a "joke", and a "scam."

Woodward's new book supposedly offers an inside look at President Trump's character and administration, but critics have pointed out the lack of solid documentation, and the sheer number of debunked claims. 

President Trump went on to accuse Woodward of making up quotes: 

The anonymously-sourced book attributes a variety of quotes to administration officials--including Generals Mattis and Kelly--who have denied saying anything like what they are accused of saying by Woodward. 

The President wrapped up his Tweet-storm by saying, "Bob Woodward is a liar who is like a Dem operative prior to the Midterms."
