Supporters of new gun laws have called for a convention to consider an amendment related to firearms. It is usually a long and complicated process, which is laid out in Article V of the Constitution.

Senate Majority Leader John Thune (R-S.D.) committed to having an “amendment process” for the Laken Riley Act as the chamber continues to work through passing the bill in the coming days.

Iowa is among 26 states that does not have a process that allows citizens an opportunity to begin the process of amending the state constitution; that process currently is started by state lawmakers.
