Counties are joining dozens of sheriff's questioning the constitutionality of the president's gun control initiatives, even suggesting they will block any federal infringement on the Second Amendment.

Johnson County is joining that group with county commissioners voting unanimously for an ordinance to that effect.

Johnson County's commissioners crafted an ordinance that would order the sheriff to ignore and even block any federal infringement on the right to keep and bear arms, including restrictions on guns and a ban on assault weapons.

If the measure passes on a final vote later this month, supporters predict that other counties will follow in defying any federal attempt to ban assault-style weapons.

Johnson would become the second county in Indiana to nullify restrictions on guns and ammunition.

Franklin County commissioners enacted a similar ordinance in January.
