Attorneys for minority groups in Texas are criticizing the makeup of four new congressional seats.

The state is getting the new seats because of mostly Hispanic population growth. But in opening statements Tuesday, attorneys argued that the new map illegally dilutes minority voting strength and that the new districts do not fairly reflect the demographics of the new population.

The GOP-drawn congressional and legislative maps are the subject of a trial before a three-judge panel in San Antonio.

Texas Attorney General Greg Abbott, whose office serves as the state's attorney, contends the map maintains or increases the ability of minority voters to elect their candidate of choice in each district.
