"WASHINGTON - The state of California filed a lawsuit on Friday seeking to force two federal agencies to provide data they used to justify rolling back landmark Obama-era vehicle emission standards, accusing the Trump administration of “willfully withholding” information.
In a lawsuit filed in U.S. District Court in Washington, D.C., California Attorney General Xavier Becerra said the National Highway Traffic Safety Administration and Environmental Protection Agency failed to respond to a Freedom of Information Act request seeking data and analysis backing their proposal to freeze federal vehicle emission standards at 2020 levels through 2026.
In addition to weaker fuel efficiency standards, the Trump administration proposal would strip California of the ability to impose stricter rules, which a dozen other states have adopted."
