Influential gun-rights groups are pushing proposals to strip cities and counties of any power to regulate guns and limit local programs to buy guns back from their owners.

The House Federal and State Affairs Committee had a hearing Thursday on the measure. It has the support of both the National Rifle Association and the Kansas State Rifle Association.

The bill would prohibit cities and counties from limiting the open carrying of firearms and bar them from spending tax dollars to administer firearms buyback programs. Besides stripping cities and counties of the power to set gun policies, the bill declares existing ordinances void.

The proposal follows enactment of a state law last year declaring that the federal government has no power to regulate guns manufactured, sold and kept only in Kansas.
