Four journalists made important contributions to this book while working as researchers during the four-year life of the project. Ben Van Huevelen, who is now the managing editor of the Iraq Oil Report, worked on that subject and ExxonMobil’s litigation with Venezuela, as well as on corporate responsibility issues in Africa and Indonesia. Megha Rajagopalan, a 2008 graduate of the University of Maryland who is now studying in China under the Fulbright Scholar Program, worked on global warming, the Exxon Valdez spill, and phthalate regulation; chapters five and twenty-two benefited greatly from her research. Ann O’Hanlon, a former Washington Post reporter who now works at the Justice Department, reported on many subjects, but especially on campaign finance and lobbying; her work particularly supported chapters three, seventeen, twenty-two, and twenty-three. Haley Cohen, a 2011 graduate of Yale University who is now on a university fellowship in Latin America, recontacted many interview subjects, checked facts and interpretations, and added fresh reporting throughout. The book benefited from other supporters and collaborators; the acknowledgments provide an accounting. I am grateful and deeply indebted to all.
