"Republicans want to repeal California’s emissions standards under a law called the Congressional Review Act. This statute allows Congress to nullify rules that were recently issued by federal agencies, and to do so with a simple majority in each chamber, bypassing the filibuster in the Senate. Once the president signs a CRA repeal into law, agencies are forever barred from passing any regulation that is “substantially the same” as the one Congress nullified. Republicans claim that the California waivers qualify as an agency “rule” subject to repeal under the CRA. And they are racing to kill it through a mechanism that would, in theory, prevent the EPA from ever granting such a waiver again."

Senate Republicans Are Poised to Deal a Shattering Blow to the Filibuster
Throughout the 2024 campaign, GOP senators shouted from the rooftops that they would preserve the tactic if they won back the chamber. Whoops.
In a message sent to thousands of employees last week, called for help in lobbying U.S. senators to overturn California’s regulation banning new gas-powered car sales by 2035. The rule, adopted by 11 other states, is now at risk as Congress prepares to vote on revoking the state’s ability to set its own emissions standards.The automaker, once an early supporter of California’s goals, is now warning that the rules don’t reflect current market conditions and could undercut affordability and choice for consumers. Although GM (GM) set an internal goal in 2021 to end sales of most gasoline-only vehicles by 2035, slowing EV sales and shifting political winds have altered the company’s calculus.
GM representative told the Journal that the company still supports electric vehicle development and continues to invest heavily in new EV models. However, the company is advocating for a single national emissions standard and regulations that reflect real-world demand trends.
The internal call-to-action email was distributed to employees in Michigan and other affected states, prompting staffers in congressional offices to report a wave of calls from GM workers."
