In California, Los Angeles prosecutors have filed criminal charges against the Southern California Gas Company over a massive ongoing methane gas leak. The company faces misdemeanor charges for failing to report the release of hazardous materials from the leak, which has been called the worst U.S. environmental disaster since the BP oil spill. California Attorney General Kamala Harris also sued the gas firm for violating health and safety laws. Thousands of people have been forced to evacuate as methane, a powerful greenhouse gas, continues to leak more than three months after the breach was revealed.
