Trump signed measures Thursday revoking waivers for the state's mandates that clean up car and truck exhaust and ramp up sales of electric vehicles. California and 10 other states immediately sued and the governor ordered the air board to craft a new mandate.

President Donald Trump is expected to sign a measure Thursday that blocks California’s first-in-the-nation rule banning the sale of new gas-powered cars by 2035.

California leaders said the state intends to challenge the move in court, and to find new ways to move drivers toward electric vehicles.
