Creates the "Protect Missouri Voters" amendment

HJR 3 proposes a constitutional amendment titled "Protect Missouri Voters" to restrict foreign influence in statewide ballot measures. It would ban contributions from foreign adversaries (as defined by U.S. designations) and foreign nationals to support or oppose such measures, with penalties including fines, imprisonment, or triple the illegal contribution amount. The amendment also criminalizes petition signature fraud, requires public hearings before initiative petitions are submitted, mandates majority approval in each congressional district for constitutional initiatives, and ensures the full text of initiatives is provided to voters with their ballots. If approved by voters, these provisions would become part of Missouri's constitution.
