Comey Book Sells More Than 600K Copies in First Week

James Comey's A Higher Loyalty had a very big opening week.

Flatiron Books announced Tuesday that sales topped 600,000 copies, a number that includes print, audio and e-books. The former FBI director's memoir had been one of the year's most anticipated releases. It includes his accounts of investigating Hillary Clinton's emails and of his awkward encounters with President Donald Trump.

Comey, fired by Trump a year ago, has likened the president to a crime boss who values personal loyalty over service to the country. Published April 17, A Higher Loyalty is the hottest political book since Michael Wolff's million-selling Fire and Fury, which came out in January.

Both books were published by imprints of Macmillan.
