Chairmen Guthrie, Joyce, and Palmer Investigate California Air Resources Board

WASHINGTON, D.C. – Today, Congressman Brett Guthrie (KY-02), Chairman of the House Committee on Energy and Commerce, Congressman John Joyce, M.D. (PA-13), Chairman of the Subcommittee on Oversight and Investigations, and Congressman Gary Palmer (AL-06), Chairman of the Subcommittee on Environment, sent a letter to Steven S. Cliff, Ph.D., Executive Officer of the California Air Resources Board (CARB), demanding answers and documents that the Committee previously requested from CARB on California’s refusal to follow the law and implement the Clean Air Act as written by Congress. The Committee also requested transcribed interviews of six individuals if CARB fails to provide the previously requested information by December 5, 2025.    “The Committee’s August 11, 2025, letter requested information and documents from the California Air Resources Board (CARB) about California’s enforcement of state vehicle emission standards that disregard recent Congressional actions to disapprove waivers of federal preemption under the Clean Air Act,” said Chairmen Guthrie, Joyce, and Palmer. “Unfortunately, CARB’s responses to date have been woefully inadequate and do not satisfy the Committee’s important oversight interests in this matter.” Key excerpt from the letter: “Clean Air Act section 209(a) preempts states from adopting or attempting to enforce any emissions control standard for new motor vehicles or engines, or any condition precedent to the initial retail sale, registration or inspection of such vehicle or engine. Under section 209(b), the U.S. Environmental Protection Agency (EPA) may waive federal preemption, allowing California to establish state motor vehicle emission standards. However, Congress passed with bipartisan support, and President Trump signed, three resolutions under the Congressional Review Act (CRA) disapproving three waivers of preemption that the Biden-Harris Administration previously granted.” “Due to CARB’s failure to make a good faith effort to provide the requested information and documents, the Committee requests transcribed interviews with the following individuals if CARB fails to provide the requested information and documents by December 5, 2025: Lauren Sanchez, CARB Chair (from September 2025 to present); Liane Randolph, Former CARB Chair (from December 2021 to September 2025); Steven Cliff, CARB Executive Officer; Shannon Dilley, CARB Chief Counsel; Christopher Grundler, CARB Deputy Executive Officer – Mobile Sources & Incentives; and Robin Lang, Division Chief, CARB Emissions Certification & Compliance Division. “The Committee requests that these transcribed interviews be completed no later than December 12, 2025.” Background: Since President Trump signed the three Congressional Review Act resolutions into law, revoking California’s ability to set state emission standards that mandate the sale of EVs, the state cannot move forward with plans to ban the sale of gas-powered vehicles. The Committee’s August 11, 2025, request sought answers about California’s apparent enforcement of the preempted standards and requested copies of related documents, such as internal guidance CARB provided to its staff, communications with other states, internal correspondence between CARB officials and the Governor’s Office and the Office of Attorney General, and other internal documents concerning CARB’s response to the disapproval of the waivers of federal preemption. The requested information and documents will help the Committee understand how California is implementing the Clean Air Act in light of the federal preemption of state emission standards, and whether the waiver authority in Clean Air Act section 209(b) should be eliminated or otherwise modified.

Chairmen Joyce and Palmer Send Letter to GAO Requesting Information on Alternatives to Critical Minerals Supply Chain

WASHINGTON, D.C. – Yesterday, Congressman John Joyce, M.D. (PA-13), Chairman of the Subcommittee on Oversight and Investigations, and Congressman Gary Palmer (AL-06), Chairman of the Subcommittee on Environment, sent a letter to Gene Dodaro, the Comptroller General of the Government Accountability Office (GAO), requesting an assessment of available or emerging technologies and materials that could be used to supplement critical minerals in semiconductors. “Critical minerals such as lithium, cobalt, and rare earth elements are essential for technologies used in many sectors of the economy, including energy, transportation, national defense, health care, and consumer electronics,” said Chairmen Joyce and Palmer . “These minerals are vulnerable to supply-chain disruptions for several reasons, including U.S. reliance on foreign sources, as well as the rapid growth in demand for critical minerals in the U.S. and abroad.” CLICK HERE to read the full letter. The letter asks the GAO to examine: The status of domestic technologies and supplemental materials, such as critical minerals found in mine waste, tailings, or reclaimed from end-of-life batteries and electronic waste, that can serve as substitutes for foreign-sourced critical minerals from non-allied nations needed for semiconductors and energy grid or power electronics, including impacts on material and product performance. Key technological challenges to the development or adoption of these domestic supplemental and materials to advance the diversification of U.S. critical mineral sources. BACKGROUND: In May, the Subcommittee on Oversight and Investigations held a hearing on ways to enhance our critical mineral supply chains. Energy and Commerce Committee Republicans are committed to strengthening our critical mineral supply chains and finding solutions to reduce our reliance on foreign sources, particularly when it comes to foreign adversaries like China. The Trump Administration has also worked hard to bolster these supply chains. Critical minerals are essential to American technologies and industries, and finding innovative domestic solutions that can contribute to our independence from non-allied nations is essential as we work to onshore American innovation and strengthen our national security. ###

Chairmen Guthrie, Joyce, and Palmer Investigate Biden-Harris Administration Decision to Fund Far-Left Groups Through the Greenhouse Gas Reduction Fund

WASHINGTON, D.C. – Today, Congressman Brett Guthrie (KY-02), Chairman of the House Committee on Energy and Commerce, Congressman John Joyce, M.D. (PA-13), Chairman of the Subcommittee on Oversight and Investigations, and Congressman Gary Palmer (AL-06), Chairman of the Subcommittee on Environment, sent a letter to Environmental Protection Agency (EPA) Administrator Lee Zeldin requesting information on how far-left organizations received billions of dollars in the final days of the previous administration through the Greenhouse Gas Reduction Fund (GGRF).  “In the final days of the Biden-Harris Administration, the EPA put their far-left allies ahead of the American people, giving away Greenhouse Gas Reduction Fund grants worth nearly $30 billion to recipients who were not equipped to receive such large amounts of funding,” said Chairmen Guthrie, Joyce, and Palmer. “By requesting documentation about this grant process from the EPA, Republicans on the Committee on Energy and Commerce are continuing our work to root out waste, fraud, and abuse while being good stewards of taxpayer dollars.”  This letter follows requests sent to eight nonprofits who were awarded more than $20 billion earlier this year through the GGRF. Key excerpt from the letter: “The Committee finds the potential for financial mismanagement particularly worrisome, as some of the grantees’ previous revenues were only a small fraction of the GGRF funds they received, which raises questions about whether the grant recipients can adequately manage grant amounts that are significantly larger than their previously documented revenue.” “The Committee seeks to ensure that the federal government is a good steward of taxpayer dollars and to continue supporting EPA’s efforts in combatting waste, fraud, and abuse within the GGRF program. To assist with the Subcommittee’s investigation of GGRF and support the Administration’s efforts, the Committee requests the following documents no later than November 19, 2025: The complete grant file for the three NCIF grantees and the five CCIA grantees, including the application submitted by the organization with all supporting documentation and appendices, any additional information requested by EPA, and any memos on changes to the grant terms and conditions. The scoring breakdown and rational for each score for all the NCIF and CCIA applicants included in the final rankings lists for the top-ranked applications, including any changes to scoring or rescores and rationale for why those changes occurred. Any checklist or guidance for EPA grants employees on what steps they should be taking to conduct appropriate pre-award due diligence and to ensure all required paperwork and documentation is submitted and verified. This should include briefing materials used to advise the Administrator, Deputy Administrator, Chief of Staff, General Counsel, Associate Administrator for Mission Support, and Associate Administrator for the Office of Air and Radiation about the selection of NCIF grantees and CCIA grantees. Any reports received from Citibank or the U.S. Treasury regarding the account balances or transactions histories of the GGRF accounts for the three NCIF grantees and the five CCIA grantees and any of their sub-awardees. Any progress reports received from the three NCIF grantees and the five CCIA grantees. The names of all panel chairs, senior review panels, selection officials, and all individuals involved in the review panels for all the NCIF and CCIA applicants included in the final rankings lists for the top-ranked applications.” Background: The Inflation Reduction Act (IRA) authorized the Environmental Protection Agency (EPA) to create and implement a $27 billion GGRF program. Of this appropriation, $20 billion was awarded to just eight grant recipients; with $14 billion awarded to three grant recipients under the National Clean Investment Fund (NCIF) program and $6 billion awarded to five grant recipients under the Clean Communities Investment Accelerator (CCIA) program.  CLICK HERE to read the full letter.
