Republican legislators in California announced Wednesday that they are sending a letter to the U.S. Department of Justice and to the U.S. Attorneys representing California, calling for a potential federal investigation into who is behind the proposed new congressional maps in California and how they were constructed.

The new map would shift five of California's Republican House seats to be more favorable to Democrats in the 2026 midterm elections.

Republican state legislators have filed an emergency petition with the California Supreme Court to put a Democratic-led mid-decade redistricting effort​ on hold.

California's Democratic Legislature is expected to counter Texas' mid-decade redraw of its congressional map with one of its own.
