WASHINGTON (AP) — Attorneys for the Justice Department and state of Texas are making their closing arguments in a Washington courtroom over whether electoral maps crafted by the Republican-dominated Texas Legislature violate the Voting Rights Act.

The three-judge panel has listened to two weeks of testimony and must decide whether the new maps of the state’s legislative and congressional districts violate a section of the federal statute that requires pre-approval from the Justice Department for states with a history of racial discrimination.
