Publisher Flatiron Books, a division of privately-owned Macmillan, said it has printed more than 1 million copies of Comey's book, which has made national headlines.Flatiron did not say whether the first week sales were global or limited to the United States.
Comey has been on a media blitz, sitting for numerous television and radio interviews, while also on a book tour that has seen him appear before sold-out audiences of more than a thousand.
The book has drawn Trump's ire as Comey compared the president to a mob boss who stresses personal loyalty over the law and has little regard for morality or truth.
