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

HB 4 establishes new congressional district boundaries for Texas voters to be used in the 2026 U.S. House elections. It adopts the PLANC2308 redistricting plan based on 2020 Census data (TIGER/Line Shapefiles) to define district lines. The bill replaces all prior Texas congressional district maps, including those from 2021, and applies to elections starting with the 120th Congress (2026). This is a procedural redistricting bill directly affecting Texas residents' voting districts for federal elections beginning in 2026.
