A panel of federal judges has blocked Texas’ newly-redrawn congressional map — which made five districts in the state more favorable to Republicans — saying the plan appeared to be an illegal race-based gerrymander.

In a 2-1 ruling, the court ordered Texas to rely instead on the boundaries legislators drew in 2021. The new map, the majority concluded, appears likely to be unconstitutional and was drawn at the urging of the Trump administration.

“The map ultimately passed by the Legislature and signed by the Governor — the 2025 Map — achieved all but one of the racial objectives that DOJ demanded,” U.S. District Judge Jeffrey Brown, a Galveston-based Trump appointee, wrote for the panel majority.

The decision is a massive blow in the White House’s push to redistrict across the country. Texas’ five-seat map represented the biggest gains for the GOP through redrawing. Republicans are expected to immediately appeal the ruling.
