President Donald Trump signed a resolution on Thursday that blocks California’s first-in-the-nation rule banning the sale of new gas-powered cars by 2035.

The resolution was approved by Congress last month and aims to quash the country’s most aggressive attempt to phase out gas-powered cars. Trump also signed measures to overturn state policies curbing tailpipe emissions in certain vehicles and smog-forming nitrogen oxide pollution from trucks.

Trump called California’s regulations “crazy” at a White House ceremony where he was expected to sign the resolutions.

California is expected to challenge Trump's latest move targeting its vehicle standards rules in court.

"Trump’s all-out assault on California continues – and this time he’s destroying our clean air and America’s global competitiveness in the process," Newsom said. "We are suing to stop this latest illegal action by a President who is a wholly-owned subsidiary of big polluters."

The three resolutions Trump signed will block California’s rule phasing out gas-powered cars and end the sale of new ones by 2035. They also kill rules that phase out the sale of medium- and heavy-duty diesel vehicles and cut tailpipe emissions from trucks.

Newsom, who is considered a likely 2028 Democratic presidential candidate, and California officials contend that what the federal government is doing is illegal.

The signings come as Trump has pledged to revive American auto manufacturing and boost oil and gas drilling.

The move follows other moves the Trump administration has made to roll back rules that aim to protect air and water and reduce emissions that cause climate change.

The Environmental Protection Agency on Wednesday proposed repealing rules that limit greenhouse gas emissions from power plants fueled by coal and natural gas.

Dan Becker with the Center for Biological Diversity, said the signing of the resolutions was “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.

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 Democratic 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.
