WASHINGTON (AP) — 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, a White House official told The Associated Press.
The resolution Trump plans to sign, which Congress approved last month, aims to quash the country’s most aggressive attempt to phase out gas-powered cars. He also plans to approve measures to overturn state policies curbing tailpipe emissions in certain vehicles and smog-forming nitrogen oxide pollution from trucks.
The timing of the signing was confirmed Wednesday by a White House official who spoke on condition of anonymity to share plans not yet public.
The development comes as the Republican president is mired in a clash with California's Democratic governor, Gavin Newsom, over Trump's move to deploy troops to Los Angeles in response to immigration protests. It's the latest in an ongoing battle between the Trump administration and heavily Democratic California over everything from tariffs to the rights of LGBTQ+ youth and funding for electric vehicle chargers.
“If it’s a day ending in Y, it’s another day of Trump’s war on California,” Newsom spokesperson Daniel Villaseñor said in an email. "We’re fighting back."
According to the White House official, Trump is expected to sign resolutions that block California’s rule phasing out gas-powered cars and ending the sale of new ones by 2035. He will also kill rules that phase out the sale of medium- and heavy-duty diesel vehicles and cut tailpipe emissions from trucks.
The president is scheduled to sign the measures and make remarks during an event at the White House on Thursday morning.
Newsom, who is considered a likely 2028 Democratic presidential candidate, and California officials contend that what the federal government is doing is illegal and said the state plans to sue.
Transportation Secretary Sean Duffy, Energy Secretary Chris Wright and Environmental Protection Agency Administrator Lee Zeldin are expected to attend, along with members of Congress and representatives from the energy, trucking and gas station industries.
The signings come as Trump has pledged to revive American auto manufacturing and boost oil and gas drilling.
The move will also come a day after the Environmental Protection Agency proposed repealing rules that limit greenhouse gas emissions from power plants fueled by coal and natural gas. Zeldin said it would remove billions of dollars in costs for industry and help “unleash” American energy.
California, which has some of the nation’s worst air pollution, has been able to seek waivers for decades from the EPA, allowing it to adopt stricter emissions standards than the federal government.
In his first term, Trump revoked California’s ability to enforce its standards, but President Joe Biden reinstated it in 2022. Trump has not yet sought to revoke it again.
Republicans have long criticized those waivers and earlier this year opted to use the Congressional Review Act, a law aimed at improving congressional oversight of actions by federal agencies, to try to block the rules.
That’s despite a finding from the U.S. Government Accountability Office, a nonpartisan congressional watchdog, that California’s standards cannot legally be blocked using the Congressional Review Act. The Senate parliamentarian agreed with that finding.
California, which makes up roughly 11% of the U.S. car market, has significant power to sway trends in the auto industry. About a dozen states signed on to adopt California's rule phasing out the sale of new gas-powered cars.
The National Automobile Dealers Association supported the federal government’s move to block California’s ban on gas-powered cars, saying Congress should decide on such a national issue, not the state.
The American Trucking Associations said the rules were not feasible and celebrated Congress’ move to block them.
Chris Spear, the CEO of the American Trucking Associations, said in a statement Wednesday: “This is not the United States of California.”
It was also applauded by Detroit automaker General Motors, which said it will “help align emissions standards with today’s market realities.”
“We have long advocated for one national standard that will allow us to stay competitive, continue to invest in U.S. innovation, and offer customer choice across the broadest lineup of gas-powered and electric vehicles,” the company said in a statement.
Dan Becker with the Center for Biological Diversity, in anticipation of the president signing the measures, said earlier Thursday that the move would be “Trump’s latest betrayal of democracy.”
“Signing this bill is a flagrant abuse of the law to reward Big Oil and Big Auto corporations at the expense of everyday people’s health and their wallets,” Becker said in a statement.
