A federal court has upheld the new congressional map approved by California voters last month, giving Democrats a chance to counter the nationwide redistricting effort led by President Trump and his Republican allies.

The court challenge to the redistricting plan had been brought by the California Republican Party and the U.S. Department of Justice. The court found that the new district map did not violate laws against racial gerrymandering.

The Republicans argued that the new map was motivated by a desire to increase the voting power of Latinos. The court, in a two-to-one ruling, rejected that claim, noting that voters approved the measure, called “Proposition 50” and there was no evidence they acted on racial grounds.
