From Pro Publica:
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. ...
Experts say adding Social Security data to SAVE could help election officials verify, en masse, if voters are U.S. citizens, but it shouldn’t be used to make final determinations that people aren’t citizens.
That’s because multiple audits and analyses have shown that SSA’s citizenship information is often outdated or incomplete, especially for people who became naturalized citizens. With the 2026 midterms about a year away, Caren Short, director of legal and research for the League of Women Voters of the United States, said she fears the expanded use of SAVE will lead to errors. ...
Still, Leland Dudek, acting SSA commissioner until early May, told ProPublica he doesn’t trust that DHS will accurately flag noncitizens as officials try to cross-match data and files from multiple systems.
“They are probably going to make some massive mistakes,” he said. ...
