More than 20 House Republicans, led by Energy and Commerce Chairman Rep. Brett Guthrie (R-KY), are calling on the Transportation Department to quickly finalize its rule to overhaul vehicle fuel economy standards.

Guthrie, along with Republican colleagues, sent a letter to the Secretary of Transportation Sean Duffy on Thursday in support of the agency’s proposed changes to the Corporate Average Fuel Economy, or CAFE standards. The lawmakers argued that the existing standards, implemented by the Biden administration, effectively mandated electric vehicles and reduced consumer options.
