April 24 (UPI) -- More than 600,000 copies of former FBI Director James Comey's memoir were sold in its first week, publisher MacMillan's Flatiron Books said.
The disclosure comes amid Comey's press tour promoting his book, A Higher Loyalty: Truth, Lies and Leadership. The ex-FBI head has appeared on ABC's "20/20," and segments on national news networks to speak about his time as FBI director.
