Relating to the composition of the districts for the election of members of the United States House of Representatives from the State of Texas.

SB 4 establishes new boundaries for Texas' 38 congressional districts, defining which counties and specific subdivisions (like portions of Bowie and Harris counties) belong to each district. It directly affects Texas voters by determining which geographic areas elect representatives to the U.S. House of Representatives. The bill specifies exact county compositions and tract details for each district, such as District 1 covering East Texas counties and parts of Bowie County, and District 2 including sections of Harris County. These changes will govern how Texas residents are grouped for congressional elections starting in the next cycle. The bill passed the Texas Senate on August 12, 2025.
