SACRAMENTO, California — Attorney General Rob Bonta said on Thursday that California will sue the Trump administration to protect its ability to set its own vehicle emissions rules.

Bonta said he would file the lawsuit whenever President Donald Trump signs off on Congress’ vote on Thursday to overturn California’s phase-out of gasoline-fueled cars and trucks. It would mark his 23rd lawsuit against the Trump administration this year.

“The federal government’s overreach is illogical,” Bonta said in a press conference in Sacramento. “It’s politically motivated, and it comes at the expense of Californians’ lives and livelihoods.”

The Senate earlier Thursday voted 51-44 to overturn the Biden administration’s approval of two of California’s latest vehicle rules using the Congressional Review Act, changing the Senate’s rules to proceed with the vote despite the finding of the Senate parliamentarian and the Government Accountability Office that the waivers were beyond the reach of the CRA. The Trump administration is expected to sign the resolutions into law in the coming weeks.
