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 vote clears the way for Gov. Greg Abbott to sign the map into law and sets up a path for Republicans to gain up to five additional seats in the House.

The lawsuit, filed on behalf of 13 Texas residents, states that the redrawn districts in the new map — which Gov. Greg Abbott says he’ll “swiftly” sign into law — are racially discriminatory and violate voter protection laws.
