WASHINGTON — In a significant move, a prominent House committee has issued a subpoena to a California official, accusing her agency of withholding crucial documents in an ongoing seven-month probe into the state’s electric vehicle (EV) policy. This development was disclosed in a letter acquired by The Post.

On Monday, the House Energy and Commerce Committee formally requested communications and documents from California Air Resources Board Chair Lauren Sanchez. The request centers on regulations that aim to phase out gas-powered vehicles in favor of EVs by the year 2035, as outlined by California authorities.

House Energy and Commerce Chairman Brett Guthrie (R-Ky.) expressed concerns about the mandate, stating, “Forcing Americans to buy unreliable, and costly, EVs would eliminate consumer choice, strain our electric grid, raise costs, and increase our reliance on entities tied to the Chinese Communist Party.” He emphasized the need for transparency, urging California to respond to the subpoena promptly and cooperatively.

In response, a spokesperson for the California Air Resources Board noted that the agency has previously shared information and documents with the committee. The spokesperson highlighted California’s “longstanding authority under the Clean Air Act” and CARB’s commitment to safeguarding public health and welfare within the state.

The spokesperson further stated, “CARB’s goal is to support the Committee’s legislative inquiry through a transparent, cooperative exchange of information.”

“CARB’s goal is to support the Committee’s legislative inquiry through a transparent, cooperative exchange of information,” the rep added.

The Biden administration had signed off on waivers for California to impose the regulations — but President Trump nullified the waivers last June in response to three resolutions that passed on a bipartisan basis in the House and Senate.

At a White House bill-signing event, Trump boasted that the three Congressional Review Act resolutions would “kill the California mandates forever.”

But Guthrie wrote in a letter accompanying the subpoena that California has still been “denying auto manufacturers approval to bring vehicles to market unless the manufacturers agreed to comply with the regulations that had already been nullified through these CRA resolutions.”

“After months of negotiations, CARB’s lack of cooperation with this investigation requires the issuance of compulsory process,” Guthrie told Sanchez in the missive.

The CRA resolutions targeted waivers that had allowed the state to impose higher vehicle pollution standards than are in effect at the federal level under provisions of the Clean Air Act.

Those standards — such as the Advanced Clean Trucks (ACT), Advanced Clean Cars (ACC) and Heavy-Duty Omnibus Law-NOx regulations — were championed by California Gov. Gavin Newsom and later became a template for more than a dozen other states.

Section 209(b) of the Clean Air Act prohibits states from implementing emissions standards on new cars or engines that differ from those imposed by the federal government, unless they obtain a waiver.

Newsom, California Attorney General Rob Bonta and the California Air Resources Board shortly after joined with a group of 10 other state AGs to sue the Trump administration for disapproving of the waivers for EV regulations in June.

That’s led to a lengthy federal court battle, which is currently being heard by the San Francisco-based Ninth Circuit Court of Appeals.

Newsom also signed an executive order in June 2025 following the revocation of California’s waivers asking CARB to submit another proposal that would help the state transition from fossil fuels.

In March, the Department of Justice fired back with a suit against California over a fuel economy regulation that the Trump administration has also seen as effectively an EV mandate.

The House committee, which began its probe in August, noted in its letter that it was specifically seeking “communications between CARB and the California Governor’s Office and the California Attorney General’s office.”

“Reviewing these documents and communications is vital to understanding what actions, including actions related to enforcement and implementation of the aforementioned laws and regulations, the state of California has taken thus far with respect to its new vehicle and new motor emission reduction plans following the CRA resolutions signed into law last year,” Guthrie said.
