The Texas Senate gave final approval to a new, Republican-leaning congressional voting map early Saturday, sending it to Gov. Greg Abbott for his signature.

President Donald Trump has pushed for the map to help the GOP maintain its slim majority in Congress in the 2026 midterm elections. It has five new districts that would favor Republicans.

Abbott, a Republican, is expected to quickly sign it into law, though Democrats have vowed to challenge it in court.

The effort by Trump and Texas’ Republican-majority Legislature prompted state Democrats to hold a two-week walkout and kicked off a wave of redistricting efforts across the country.
