California, 26 states sue Trump admin over rollback of fuel efficiency standards

California and 26 other states filed a lawsuit challenging the Trump administration's rollback of federal vehicle fuel economy standards, reversing Biden-era environmental protections. The legal action, led by California AG Rob Bonta, marks a direct state-federal confrontation over climate policy. The outcome is uncertain and could hinge on judicial interpretation of federal preemption and state authority under the Clean Air Act.
