A federal court has issued a proposed interim map for Texas voting lines for the 2012 election.
The new map will override the original map approved by the Texas legislature.
Texas lawmakers redraw district lines every 10 years to compensate for population growth. Texas gained four additional seats in due to the state's population growth.
Minority groups are contesting the state approved map saying it illegally weakens their voting power.
Republicans defend the map saying they drew the map to increase their power, not to weaken minorities.
