Two of those seats are in South Texas, and represented by Democratic Reps. Vicente Gonzalez and Henry Cuellar, who both narrowly won reelection in 2024. Both districts, which Trump carried in 2024, would become more Republican under the redrawn district lines.

Despite protests from Democrats, a Texas House committee advanced a draft congressional map Saturday that could add five new Republican districts next year.

The bill is now headed to the Texas House for a vote on the floor. If passed, political analysts say the new map could create as many as five more Republican seats in Congress by shifting seats in major urban centers like Dallas, Austin and Houston. The first steps in that process could begin as early as the beginning of next week.
