Missouri's House has endorsed a proposed amendment to the state Constitution intended to strengthen the right to bear arms.
The Republican-led chamber voted 122-31 on Tuesday to send the bill back to the Senate where a similar version passed previously. Lawmakers must agree on an identical bill before the session ends May 16.
Legislative approval would put the measure on the November statewide ballot.
The amendment would define the right to bear arms as "unalienable" and require the state to defend against any "infringement" of that right. It would also include defending one's "family" with a firearm as a guaranteed constitutional right.
It would also specify that the Legislature could still impose restrictions on gun ownership for convicted violent felons and the mentally ill.
