State legislatures this week in at least two states advanced measures aimed at halting current or future federal laws affecting the Second Amendment.
In Montana, the state House passed a bill by a 58-42 vote Monday to prohibit enforcement of new federal weapon and magazine bans in the state, sending it to the Senate for consideration. Meanwhile, lawmakers in an Arizona Senate committee gave their stamp of approval to similar but more expansive legislation in a 4-2 vote Tuesday. In each case, votes were largely along party lines with Republicans casting for and Democrats against.
