Democratic lawmakers are trying to build a case that Republicans in Texas have engineered a rushed and unfair process for redrawing the state’s congressional districts.

Texas Republicans are powering ahead with an aggressive strategy backed by President Donald Trump to seize control of multiple Democratic seats in next year’s critical midterm: redrawing the state’s congressional map in favor of more GOP seats.

The new proposed lines would also prevent few, if any, opportunities for Democrats hoping that an aggressive gerrymander could backfire on Republicans.
