Senate Republicans could vote this week to take away California's ability to impose tough limits on car emissions — a move Democrats call unprecedented.

Senate Republicans have voted to establish a new precedent that will allow them to roll back clean air standards in California, including a rule phasing out the sale of new gas-powered cars by 2035.

The Republican-led Senate moved Wednesday to overturn key Biden-era waivers allowing California to set its own vehicle emissions, a major blow to that state’s effort to regulate pollution from cars and trucks that could have broad environmental impacts for the rest of the country.
