The Justice Department has asked the FBI to evaluate whether oil giant ExxonMobil broke federal laws by lying to investors and the public about climate change. The move comes in response to a request from California Congressmembers Ted Lieu and Mark DeSaulnier. They are seeking a federal investigation of Exxon following exposés by InsideClimate News and the Los Angeles Times revealing Exxon knew that fossil fuels cause global warming as early as the 1970s but hid that information from the public and instead poured millions into climate denial. California Attorney General Kamala Harris and New York Attorney General Eric Schneiderman have also launched investigations into Exxon.
