Revise campaign finance laws to limit certain tax-exempt organization contributions

This bill limits contributions from certain tax-exempt organizations, specifically those exempt under section 501(c)(4) of the Internal Revenue Code, to political and joint fundraising committees in Montana. It caps such contributions at $2,500 per organization for supporting or opposing candidates or ballot measures and completely prohibits these organizations from making direct contributions to candidates. Additionally, the bill bars any tax-exempt organization from contributing to political committees if it has received a donation from a foreign national within the previous four years. Violations of these contribution limits are subject to civil penalties under existing state law.
