Requires enhanced reporting of campaign contributions and expenditures by independent expenditure committees.

This bill would require independent expenditure committees (often called "dark money" groups) to report campaign contributions over $7,500 and expenditures over $200 more frequently and with greater detail. Committees would need to report these contributions and expenditures within 72 hours (or 24 hours if within a week of an election) before elections. The bill also mandates quarterly post-election reports until campaign accounts close, including detailed information about contributors such as occupation and employer. This addresses a transparency gap in current law that allowed these groups to operate without disclosing contributions and spending in the critical period before elections.
