On Tuesday, a group of nonprofits and private citizens sued DHS, SSA, and DOJ, alleging “a months-long campaign to access, collect, and consolidate vast troves of personal data about millions of U.S. citizens and residents stored at multiple federal agencies,” centralized at a USCIS “data lake.”

Per the complaint, this includes the pooling of data in the immigration-related SAVE database and distinct Social Security records (which NPR was on top of from the beginning), along with the voter rolls that DOJ’s been after and DOGE teams thrown in the mix. And on both the voter file side and the SAVE side, the complaint asserts (inter alia) violations of the Privacy Act along the same lines I’d been flagging.

This is a case to watch.
