IMMIGRATIONDetails of DHS Agreement Reveal Risks of Trump Administration’s Use of Social Security Data for Voter Citizenship Checks
A recently released agreement gives the Department of Homeland Security access to hundreds of millions of Americans’ Social Security data. It contains alarmingly few provisions to ensure accuracy and privacy, experts say.
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.
The initial results, however, didn’t exactly back up President Donald Trump’s contention that noncitizen voting is widespread. Texas identified 2,724 “potential noncitizens” on its rolls, about 0.015% of the state’s 18 million registered voters. Louisiana found 390 among 2.8 million registered voters, a rate of about 0.014%.
Instead, experts say, the sweeping data-sharing agreement authorizing DHS to merge Social Security data into SAVE could threaten Americans’ privacy and lead to errors that disenfranchise legitimate voters.
The details of the agreement, which haven’t previously been reported, show it contains alarmingly few guardrails to ensure accuracy and scant specifics on how the data will be kept secure, election and privacy lawyers who have reviewed it say. Further, it explicitly does not bar DHS from deploying the SSA data for other purposes, including immigration enforcement.
Experts have raised similar concerns about other parts of the Trump administration’s data-pooling drive, which has sought to tap all sorts of traditionally tightly controlled federal information, even tax data.
Until this year, SAVE contained information only on immigrants who’d had contact with DHS, such as those with permanent resident status, and had been assigned immigrant identification numbers. State and local officials typically used the system to verify immigrants’ status when they applied for benefits such as SNAP or to check, one by one, whether individuals who were registering to vote were citizens.
Under the May 15 data-sharing agreement, which was posted recently on the Social Security Administration’s website, the system added information, including full Social Security numbers, on millions of Americans not in DHS databases. The combined dataset joins together this information with addresses, birth dates and criminal records, along with immigration histories.
