HB 888 prohibits political campaign committees formed to support or oppose a ballot measure from accepting contributions or expenditures from foreign nationals. It requires these committees and individuals making independent expenditures on such measures to disclose funding sources to Tennessee’s election finance registry within 48 hours. The law defines "foreign national" broadly to include foreign governments, entities, and individuals not U.S. citizens or permanent residents. It also mandates committees to certify no foreign funding supported preliminary activities like polling or drafting ballot language. The law became effective May 21, 2025, after being signed by the governor.
