This bill prohibits the federal government from spending any money to finalize, implement, or enforce a specific firearms regulation proposed by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). The regulation in question, known as Rule 2022R-17, would expand the definition of who qualifies as a firearms dealer required to conduct background checks on gun sales. The bill, introduced by Representative Andrew Clyde and supported by dozens of Republican lawmakers, targets a rule that was proposed in August 2023 and argues the regulation is unconstitutional. By blocking federal funding for this rule, the legislation effectively prevents the ATF from enforcing stricter background check requirements on private gun sellers. No specific funding amounts or implementation timelines are included in the bill.
