LOS ANGELES (AP) — The fight over California's new congressional map aimed at assisting Democrats in flipping several U.S. House seats commenced in court on Monday. A panel of federal judges is evaluating the legality of the districts newly sanctioned by voters in November as part of Proposition 50.

In Los Angeles, the hearing sets a critical stage for a contentious legal and political battle between the Trump administration and California's Democratic Governor Gavin Newsom, who has been eyeing a presidential run in 2028. The lawsuit seeks a temporary restraining order to prevent the new map from being utilized in elections until a ruling is finalized by December 19—the date candidates may officially declare their campaigns for the 2026 elections, pivotal for controlling the House.

Voters approved the new House map last month, aimed at potentially flipping five seats in the midterms. The initiative represents Newsom’s response to Republican redistricting efforts in Texas supported by former President Trump.

The conflict has implications that stretch beyond California, with a critical focus on which party will control Congress in the latter part of Trump's term. Other states such as Missouri, North Carolina, and Ohio have also enacted new district lines favoring particular parties.

The situation boiled down to claims that California is employing gerrymandering tactics, violating constitutional provisions by using race as a determining factor. Republicans are pushing to block the new map, while state Democrats express confidence that the lawsuit will be quashed.

Newsom’s representative, Brandon Richards, emphasized that both California and Texas's maps were created for lawful reasons, arguing that this Republican lawsuit is an effort to suppress California voters.

The lawsuit references studies affirming that the new map expands Latino voting power and maintains the integrity of Black majority districts. The contentious nature of this case exemplifies the ongoing political maneuvering and strategic electoral planning as the nation approaches an essential election cycle.
