Missouri Republicans have outlined a new approach to prevent federal agents from enforcing gun control laws the state considers to be infringements on gun rights.
Under the bill endorsed by a Senate committee, federal agents who enforce those laws would be banned from future service in any state or local law enforcement agency.
The change comes as House and Senate backers try to reach a compromise on the legislation that has been passed separately by each chamber. The current version is pending in the Senate.
Supporters say the measure would make federal agents think twice before enforcing a gun control law. But the new approach is unlikely to sway opponents of the measure, who still say it is unconstitutional because states cannot nullify federal laws.
