Exxon Mobil's disregard for the health of the planet isn't the only thing that is disturbing about the prospect of a State Department led by Tillerson. The company and its CEO have shown shaky regard for the traditions of free speech and transparency and have attacked the credibility of professional journalists. After nongovernmental organizations, including the one I work for, criticized Exxon's decades of climate deception, the company used legal processes to bully us and repeatedly accused us of "conspiracy," a criminal act. When investigated for possible fraudulent statements to its shareholders on its understanding of climate science and how it accounts for its oil reserves, Exxon Mobil sued the Massachusetts and New York attorneys general rather than root out any internal corporate wrongdoing.
