Comey’s ‘Higher Loyalty’ a bestseller even before release

James Comey’s book “A Higher Loyalty” won’t be available to purchase until Tuesday, but it's already a bestseller.

The book, which offers a look at the former FBI director’s interactions with President Donald Trump was ranked as the #1 best-selling book on Amazon Monday morning, with interest in the book increasing after details of the book’s content were leaked.

Comey said that Trump was “morally unfit” to be president in an interview with ABC News that aired Sunday night. But, even before his interview leaked, details of the book painted Trump in a less-than-flattering light.

“This president is unethical, and untethered to truth and institutional values,” Comey says in the book, according to a New York Times review. “His leadership is transactional, ego driven and about personal loyalty.”

Trump has already taken to twitter to respond to Comey’s  book calling him a “proven LEAKER & LIAR.”

Comey was fired by Trump last May. Comey has also been criticized by Democrats for reopening the investigation into Hillary Clinton’s emails just days before the 2016 presidential election.
