A handful of Arizona Republicans are behind a push to make their state the fifth to keep state resources from assisting in any federal activity they consider contrary to the Second Amendment.

State Rep. Leo Biasiucci, R-Lake Havasu City, filed the Second Amendment Firearm Freedoms Act on Jan. 14. Like other measures, it would ban the use of local resources from enforcing any federal law or executive rule that could be seen as running afoul the constitutional right to bear arms.
