Modifies provisions relating to campaign finance in ballot measure elections

SB 1133 modifies Missouri campaign finance rules for ballot measure elections by requiring committees, donors, and entities making expenditures to affirm that contributions or funds come from permissible sources. It mandates that donors giving over $2,000 must confirm they are not foreign nationals and have not received more than $10,000 from prohibited sources in the past 2 years (individuals) or 4 years (entities). Committees and expenditure entities must similarly affirm compliance in disclosure reports and within 48 hours of spending, with violations subject to attorney general action. The bill aims to prevent foreign influence in local ballot measures, declaring it an emergency for public safety.
