Former FBI Director James Comey's book, which portrays US President Donald Trump as egocentric and dishonest, paralleling his methods with that of the mafia, sold 600.000 copies in one week in the United States, according to the United States.
The book "A Higher Loyalty: Truth, Lies and Leadership" was released on April 17 and is currently the second best-selling bookstore on the Amazon online bookstore. It is also in the top twenty best-selling books in Germany, Australia and the UK.
Another book about Trump, Michael Wolf's Fire and Fury, was a huge success when it first came out in early January after selling more than 1 million copies in its first week.
To date, the controversial book depicting life in the White House under Donald Trump has sold more than 2 million copies, according to the New York Times.
Flatiron Books has printed about 1 million copies of the book by Comey, the 57-year-old former federal prosecutor who was fired by Trump.
The book angered the president, who described Comey as a "liar."
