Federal authorities has officially joined a legal challenge brought forward by California Republicans, seeking to halt the state's recently passed congressional redistricting map.
This court case, filed in a US district court, challenges the map supported by Governor Gavin Newsom, which was developed in response to a GOP redistricting effort in Texas.
"The state's electoral map constitutes a brazen power grab that violates civil rights and mocks the electoral system," stated the nation's top law enforcement official.
The Democratic party have expressed confidence that the new maps will withstand court challenges.
"The plaintiffs were defeated in the election and they are likely to face defeat in the judicial system," stated a representative for the governor.
The legal challenge asserts that California's map improperly used race as a factor to heavily favor Hispanic voters in contravention of the US Constitution.
"Race cannot be used as a substitute to further partisan goals, but that is precisely what the state legislature did with the redistricting measure," stated a senior official from the DOJ's civil rights unit.
This courtroom confrontation constitutes the major response by the Democratic party in the ongoing political battle that began in Texas and has extended to various parts of the country.
Unlike other states, where Republican state legislatures have enacted gerrymanders, California's plan required public consent, which it obtained with nearly 65% of the vote.
The Democratic party need to gain just a small number of Republican-held House seats to gain majority of the chamber in next year's congressional elections.
The political group controlling the majority will shape the final years of the sitting president's term, deciding if a unified Republican Congress will continue to deliver its political program or face resistance, investigations and possible additional obstacles.
