The DOJ says that when states accept federal funds to assist low-income families, all state agencies have to report people’s immigration statuses. It’s likely that certain states, especially those that are led by Democrats, will challenge the new legal interpretation in court. Michael M.

Attorneys general in several states have already pushed back against previous attempts from the Trump administration to force local agencies to share information about immigration status with the federal government alongside other immigration enforcement efforts.
