Houston Sen. Carol Alvarado plans to filibuster a Republican bill that redraws congressional maps and adds five GOP-leaning districts, part of a Trump-backed strategy to secure House control.

All three Democrats are either declared or potential contenders for the Senate seat on the ballot in next year's midterm elections. In what would typically be a quiet period in Texas politics, Republicans have roiled the state's 2026 Senate campaign with their rush to redraw congressional maps to give Trump more allies in Congress.

Texas Democrats prepared for a final show of resistance against a Republican effort to redraw the state’s congressional maps mid-decade, with plans to push a Senate vote into the early morning hours Saturday in a last-ditch attempt to delay final passage.

The Texas Senate is reconvening Friday morning to take up a controversial GOP redistricting bill that triggered a weeks-long House standoff. The Republican-backed proposal, which passed the House in an 88-52 party-line vote on Wednesday, aims to redraw the state's congressional map and produce five new GOP-leaning districts.

Democrats in the Texas House of Representatives returned to Austin on Aug. 18, 2025, but their protest of redistricting efforts continues.

Texas lawmakers meet again Friday, when the Republican majority in the Senate could give final approval to their map.
