Former FBI director James Comey’s tell-all book is hitting shelves next week, but copies are already circulating. Its contentions will definitely stir the political pot, judging from early excerpts.

In A Higher Loyalty: Truth, Lies, and Leadership, Comey likens President Donald Trump to a mob boss, and claims Trump asked for a “loyalty oath” from him. The book also explains Comey’s controversial handling of  the Hillary Clinton email investigation

The book is officially released on Tuesday, but copies have already been obtained by the Associated Press, The Washington Post and New York Times. Comey was fired by Trump and the enmity between the two has been apparent ever since.  

Comey says Trump was creating a “cocoon of alternative reality that he was busily wrapping around all of us,” according to The Washington Post’s account. He also likened the Trump presidency to “a forest fire.”

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

Comey also claimed Trump asked for a special investigation on the wild claims contained in a dossier that was circulating.  “He brought up what he called the ‘golden showers thing’ … adding that it bothered him if there was ‘even a one percent chance’ his wife, Melania, thought it was true,” Comey wrote. Comey claimed he cautioned the president that any probe might “create a narrative” that the FBI was investigating him, the Post reported.

The Clinton email investigation is covered in a conversation he allegedly had with President Obama and former Attorney General Loretta Lynch.

“I picked you to be FBI director because of your integrity and your ability. I want you to know that nothing — nothing — has happened in the last year to change my view,” Obama told Comey, according to The Washington Post.
