Former FBI Director James Comey is getting ready to promote his book that's scheduled to be released this week -- and a new report claims he left people "stunned" during a recently taped interview with ABC News' George Stephanopoulos.

Axios reports that the former FBI director compared President Donald Trump to a "mob boss" in the upcoming interview, and one source tells the publication that the interview will "certainly add more meat to the charges swirling around Trump."

According to Axios, Comey is going to reveal information that he has never discussed before -- and the publication's source predicts that Comey is "going to shock the president and his team."

Comey's book, titled "A Higher Loyalty: Truth, Lies, and Leadership," is set to release on April 17. White House aides are reportedly already concerned about Trump's reaction to Comey's book, and one former administration official said this week that they expected the book to be "more damaging" than Michael Wolff’s book “Fire and Fury," which topped bestseller lists earlier this year.

The ABC interview with Comey is scheduled to air at 10 p.m. on Sunday, April 15.
