The Texas Senate on Saturday approved new congressional maps drawn to help Republicans win as many as five more House seats in next year’s midterm elections.

The mid-decade map redraw adds five Republican-leaning districts and sets up a legal showdown over minority representation.

Hours after the Texas House of Representatives passed a revision of the state's congressional districts, voters filed a complaint alleging legislators created "a map that eviscerates minority representation and hands Anglo voters control of an even larger share of Texas' congressional seats."
