Lobbying, Lobbyists - As introduced, requires each lobbyist to include and maintain in the lobbyist's registration statement filed with the Tennessee ethics commission the identification of each bill and legislative measure for which the lobbyist is receiving compensation to oppose or support. - Amends TCA Title 3, Chapter 6.

HB 597 requires lobbyists in Tennessee to disclose in their registration statements with the Ethics Commission which specific bills or legislative measures they are paid to support or oppose. This change amends Tennessee law to mandate that lobbyists include this bill-specific information when filing their registration. The bill directly affects professional lobbyists who represent clients on legislative matters, adding transparency about their paid advocacy. It does not change voting rules or policy outcomes but adds a disclosure requirement for lobbying activities. The bill was introduced in 2025 but failed in committee.
