Republicans look to reverse rule based on gun law they backed

Republican backers of a once-in-a-generation gun violence bill now lead the charge against one part of the Biden administration’s implementation of the law, a falling out that illustrates the delicacy of trust required to pass legislation on hot-button issues.

A Congressional Review Act joint resolution of disapproval introduced Wednesday in the Senate by John Cornyn, R-Texas, could force the chamber to vote on overturning a rule from the Bureau of Alcohol, Tobacco, Firearms and Explosives that would expand the number of gun sellers who would be required to run background checks.

Cornyn had negotiated the 2022 gun violence prevention law that the administration relied on for the ATF rule. Now he has 41 Senate Republicans who back his joint resolution to stop that rule.
