House Bill 868 amends Tennessee campaign finance laws by prohibiting political campaign committees that are based outside of Tennessee from making contributions to candidates in primary elections within the state. Specifically, the bill states that such out-of-state committees cannot contribute to candidates in primary elections, to other political campaign committees for related activities, or for any purpose intended to influence a primary election in Tennessee.

The bill defines "primary election" as any state or local primary election held in Tennessee for a statewide political party, and it specifies that a "statewide political party" refers to the party that controls both houses of the general assembly as of July 1, 2025. This legislation is set to take effect on July 1, 2025, emphasizing the state's intent to regulate campaign contributions more strictly and ensure that local elections are not influenced by external entities.
