EXCLUSIVE — Congressional Republicans want to roll back or block efforts by mostly blue states to implement excise sales taxes on firearms, ammunition, and firearm accessories that would subsidize gun violence prevention programs and medical trauma centers.

Sen. James Risch (R-ID), ranking member of the Foreign Relations Committee, will introduce a bill Thursday to halt states or municipalities from taking such action that he says would “place a significant financial burden on law-abiding gun owners to advance [states’] anti-Second Amendment agenda.”
