The Trump administration is poised to revoke California’s authority to set auto mileage standards, asserting that only the federal government has the power to regulate so-called greenhouse gas emissions and fuel economy. Conservative and free-market groups have been asked to attend a formal announcement of the rollback set for afternoon at Environmental Protection Agency headquarters in Washington. Gloria Bergquist, spokeswoman for the Alliance of Automobile Manufacturers, said Tuesday that her group was among those invited to the event featuring EPA Administrator Andrew Wheeler and Transportation Secretary Elaine Chao. The move comes after the Justice Department recently opened an antitrust investigation into a deal between California and four automakers for tougher pollution and related mileage requirements than those sought by President Trump. Trump also has sought to relax Obama-era federal mileage standards nationwide, weakening a key effort by his Democratic predecessor to slow climate change.
