DHS Agreement Reveals Risks of Using Social Security Data for Voter Citizenship Checks

This year, when states began using an expanded Department of Homeland Security system to check their voter rolls for noncitizens, it was supposed to validate the Trump administration’s push to harness data from across federal agencies to expose illicit voting and stiffen immigration enforcement.

DHS had recently incorporated confidential data from the Social Security Administration on hundreds of millions of additional people into the tool, known as the Systematic Alien Verification for Entitlements, or SAVE, system. The added information allowed the system to perform bulk searches using Social Security numbers for the first time.
