Khashoggi. Regarding this conversation, Lombardi wrote "I began taking notes, then sketching out a simple tree chart, showing the breakdown of Khashoggi's American holdings. Within days, I began making more of these charts, depicting other corporate networks I had researched. I was writing several pieces at the time and found the charts a useful, quick reference to the material at hand."
