HB 686 amends the Texas Election Code to require political committees to disclose specific information on political advertisements supporting five or more candidates who contributed to the committee in exchange for that support. Advertisements must include the names of the supported candidates, indicate that the candidates made contributions for the support, and disclose if any of the candidates created the committee. Violations result in civil penalties of up to $4,000. The Act applies to advertisements published or broadcast on or after its effective date, September 1, 2025​.
