This bill aims to enhance the enforcement of regulations against foreign funding and influence in campaigns related to constitutional amendments and local ballot questions. It introduces a new subdivision to RSA 664, defining terms such as "covered measure," "measure committee," and "prohibited source," which is identified as a foreign national. The bill mandates that measure committees must certify, under penalty of perjury, that no preliminary activities were funded by prohibited sources and maintain records of contributions and expenditures for four years. Additionally, it requires measure committees to obtain written affirmations from donors confirming they are not foreign nationals before accepting contributions, with strict penalties for non-compliance.

The legislation also prohibits foreign nationals from participating in decision-making processes related to influencing covered measures and establishes a framework for reporting and auditing compliance. The Attorney General is tasked with enforcing these provisions, and violations can result in civil penalties and the requirement to refund or disgorge contributions. The bill does not provide funding or authorize new positions but is estimated to incur costs between $15,000 and $30,000 for necessary reporting changes within the Department of State. The act is set to take effect on January 1, 2027.
