California and 22 other states filed a lawsuit on Sept. 20 against the administration of President Donald Trump.

The latest legal battle over one of Trump’s policies comes after the president said on Sept. 18 that his administration was revoking a waiver that allows California to set its own greenhouse gas and vehicle fuel-efficiency limits for passenger cars.
