How Far Will Republicans Push the Law to Undo Biden’s Agenda?

Congress and the courts have yet to establish the boundaries of the Congressional Review Act. That may come to a head with key Biden energy policies.

Republicans in Congress are preparing to decimate Joe Biden’s legacy on everything from environmental policy to public health measures — and this time, they could test the boundaries of the little-used law that lets them do it.

Under the Congressional Review Act, Congress can undo most regulations with a simple majority vote as long as the rules were enacted within a certain time frame. The Republican majority will have until about the end of April to vote to kill any regulations published after Aug. 16, 2024.

Plenty of Biden’s policies are fair game, including erasing medical debt from credit reports, requiring fossil fuel companies to pay a fee for methane emissions, limiting bank overdraft fees to $5, mandating all lead pipes be removed and replaced in the next ten years and prohibiting tobacco product sales to anyone under 21.
