Officials in Camden County, Missouri are refusing to cooperate with the ATF, according to local reports.
Officials cited a since-struck-down state law that kept police from enforcing federal gun laws.
Six top elected officials in Camden County signed a letter to the ATF saying as much, according to NPR affiliate KCUR 89.3.
Last month, a federal judge struck down the 2021 law, which prohibited local police from enforcing federal gun laws, calling it "invalid, null, void, and of no effect."
"Any and all federal firearms laws, so-called laws, in my opinion, and many others' opinion, are unconstitutional," Skelton told KCUR.
