WASHINGTON (Reuters) - The expected legal battle over President Donald Trump's plan to revoke California's authority to set stiff vehicle emissions standards separate from those established by the U.S. government appears unlikely to be resolved before next year's presidential election.
Democratic-led states and environmental groups have announced they will challenge the move by the Republican president, his latest salvo against the most populous U.S. state, and legal experts expect complex and lengthy litigation that ultimately makes its way to the U.S. Supreme Court.
