The vast majority of reporting in this book came from interviews conducted by me with primary sources. I conducted more than 70 interviews, most on the record and some with unnamed sources, to piece this story together. When a quote or thought is from an interview, I tried my very best to always use “said” in the text. If a statement came from someone's writing or a news article, I used “wrote” or “according to” to try to keep the distinction clear. Not all of the interviews I conducted made it into the book; for those of you I left out, please know you helped me shape and understand this story and I appreciate every minute of your time. The notes section that follows includes a list of citations for third-party sources, divided by chapter and listed by page number.
