Wyoming Republican Rep. Harriet Hageman over the weekend introduced legislation targeting California vehicle emissions mandates dating back to the Obama administration.

The resolution — and others likely to emerge in the coming days or weeks — is part of the administration and Republicans’ targeting of federal waivers California has received for stricter air pollution rules, which other states often follow.

Congress repealed thee Biden-era waivers last year that Republican said amounted to an electric vehicle mandate. And last month, the Trump EPA sent four more waivers to the congressional buzz saw. Hageman’s resolution was the first to emerge against that second batch.

“Today’s legislation is another step to reclaiming our authority as the national policymaker, and to stop inflicting harm on the American people in the name of climate lunacy,” Hageman, who is running for Senate to replace retiring Republican Cynthia Lummis, said in a statement.
