HB 1613 amends the Texas Election Code to prohibit the making or accepting of political contributions during a special legislative session. It extends existing restrictions applicable to regular legislative sessions to special sessions, specifying that the prohibition applies to statewide officeholders, members of the legislature whose terms do not expire in January of the next odd-numbered year, and specific-purpose committees supporting or opposing such individuals. Exceptions include contributions intended for elections held during the session or related expenses, as well as contributions to defeated incumbents or their supporting committees. The bill clarifies the handling of contributions received during the prohibited period, requiring their return within 30 days. It applies only to contributions made on or after September 1, 2025​.
