Washington, D.C. – This morning, President Donald J. Trump signed U.S. Senators’ Markwayne Mullin (R-OK), Shelley Moore Capito (R-WV), and Deb Fischer (R-NE) joint resolutions into law to permanently eliminate California’s radical electric vehicle (EV) mandates.

President Trump credited Senator Mullin as a “serious fighter” during today’s bill signing at the White House, saying: “Thanks as well to Markwayne Mullin. Senator, Markwayne, thank you. Stand up, Markwayne. Don’t fight him. He’s a serious fighter in a lot of ways and he’s a great guy, too. Thank you, Markwayne.”

“Today we put a stop to California’s costly and extreme Green New Deal agenda that has bankrupted families, created a competitive disadvantage for manufacturers, and eliminated consumer choice for hundreds of millions of American families.” said Senator Mullin. “Thankfully, President Trump has returned common-sense and sanity to the White House. It was an honor to stand beside him as he signed our resolutions into law.”

Background:

• On Thursday, May 22, 2025, the U.S. Senate passed H.J. Res. 89, Mullin Low NOx Regulation CRA, by a vote of 49-46.
• In December 2024, EPA granted California’s “Omnibus” low-NOx regulation waiver for heavy-duty highway and off-road vehicles and engines.
• In February 2025, EPA Administrator Zeldin sent over to Congress three of the Biden Administration’s rules granting waivers that allowed California to preempt federal car and truck standards approved by EPA and DOT’s National Highway Traffic Safety Administration. Zeldin’s decision to send over the rules are part of EPA’s “Powering the Great American Comeback” initiative to protect human health and the environment while restoring our economy.
