The Trump administration is attempting to block California’s new congressional map that was approved by voters last week

Question

News coverages report that after California voters passed Proposition 50, allowing legislature to draw a new congressional map, the United States Department of Justice filed a lawsuit against California Governor Gavin Newsom, as well as the Secretary of State. From the sources I saw, the new congressional map was promoted by Democrats as a method to amend districts after Republican-led redistricting in other states. The DOJ's official press release confirms that it has filed legal action and that the lawsuit argues the new proposition violates the Equal Protection Clause because the legislature allowed racial considerations, particularly the Latino demographics, to dominate how the new districts were drawn.

To fact-check the claim, I relied on the DOJ press release along with other news outlets like the BBC that summarized the case. In the DOJ's statement, it's said that California's plan "mandates racially gerrymandered congressional districts" and describes the new map as a race-based scheme that cannot be used in the 2026 presidential elections. Also included in the press release are quotes from top DOJ officials accusing California of using race as a piece for political interests and that the DOJ is requesting a federal court to halt California from enforcing the new Proposition 50 map. California officials and voting advocates dispute this framing from the DOJ and argue that the map is legal and approved by voters of the state. Judging from all these sources, it seems that the main part of the claim is factual, The DOJ/Trump administration are suing to block California's new congressional map as a result of Prop 50 passing. It is still undecided if the court will agree with the framing presented by the DOJ so it wouldn't be accurate to say the DOJ's claims are accurate, but it is a true report that this attempt by the DOJ is ongoing.

Answer 1

The claim checks out. I first looked at the source and saw this was a News Detective post summarizing news coverage, so I looked for stronger sources. The original source is the U.S. Department of Justice, which announced on Nov. 13, 2025 that it sued Governor Gavin Newsom over California’s Proposition 50 redistricting plan, arguing the new map was race-based and unconstitutional. Proposition 50 did allow California to use a new legislature-drawn congressional map after voters approved it in November 2025. PBS/AP and Reuters also reported that the DOJ was trying to block the new congressional map, so the claim is accurate, though it is framed from the perspective of the lawsuit.
