A federal judge said that the Trump administration’s decision to adjust its census gathering deadline violated an order she issued last week.

The U.S. Census Bureau tweeted Monday that the secretary of commerce set an Oct. 5 target date to conclude 2020 Census self-response and field data collection. In a Zoom hearing Tuesday, U.S. District Judge Lucy Koh of the Northern District of California said that the announcement in the tweet—which landed minutes before a case management conference in the lawsuit—appears to be based on a plan to wrap up census field operations ahead of schedule, which she enjoined in a Sept. 24 preliminary injunction.
