The book as a literary composition is decent, but this guy is beyond hypocrisy. He talks the talk, but clearly didn't walk the walk. He mentions Christians paying lip service to Christ and then failing to live up to his principles. He claims to be a man of great faith, and then says he was proud to work for Trump, a pathological liar who pays off porn stars and commits countless other sins.
He makes much of being a devout Christian in this book.
Given the nature and behavior of the man he "proudly" served and admires, I don't think Jesus would agree.
