Oklahoma Attorney General Gentner Drummond announced a victory against the Biden Administration's vehicle emissions standards. Oklahoma, along with 21 other states, challenged the Federal Highway Administration's regulations, arguing they were designed to phase out gas-powered vehicles, according to the Oklahoma Attorney General.

The Biden Administration's regulations faced strong criticism and a legal challenge led by Kentucky Attorney General Russell Coleman. He argued they were both financially burdensome—costing over $600,000 per state just to set targets—and an environmentally coercive measure. Over the past few years, these rules aimed to support a "green agenda" linked to the previous administration's sustainability goals, as reported by the Oklahoma Attorney General.

In April 2024, a federal judge ruled the Federal Highway Administration's emissions regulation unlawful, prompting an appeal by the Biden Administration. After taking office, President Trump withdrew the appeal, effectively nullifying the rule. Drummond commented on the decision, stating, “The Biden Administration’s zeal for federal overreach was seemingly insatiable, particularly when it came to attacking the oil and gas industry.” Attorneys general from multiple states supported the withdrawal. The ruling and subsequent actions remain part of the broader discussion on environmental regulations and economic policy, as stated by the Oklahoma Attorney General.
