A federal whistleblower has accused the Department of Homeland Security of directing immigration officers to misrepresent themselves in order to access state voter databases, part of a sweeping hunt for "unlawful voters" that critics say is now ensnaring naturalized U.S. citizens by mistake.

The disclosure, nearly 30 pages long, was made public Monday by Senate Minority Leader Chuck Schumer and Sen. Alex Padilla of California, both Democrats, after being provided to Padilla's office by the legal nonprofit Democracy Defenders Fund, whose client asked to stay anonymous over "extreme fear of retaliation." The whistleblower is a USCIS officer pulled into DHS's "Unlawful Voter Initiative," launched in late August.

According to the report, officers from USCIS's Fraud Detection and National Security Directorate were diverted from their normal national-security casework and told to log onto public-facing state election websites while falsely claiming to be voters or to have voter authorization — conduct the whistleblower says may violate state law in multiple jurisdictions. Padilla's office says the account points to "potentially thousands" of such violations.

The numbers described in the disclosure are stark: officers were given quotas of roughly 40 individuals a day — about 12 minutes each — to determine whether someone is a lawful voter, after training that reportedly amounted to a single 1-hour-45-minute video, according to NPR's reporting on the disclosure. Anyone flagged gets a federal law enforcement file, known as a TECS record, created against them — including, the whistleblower says, naturalized citizens wrongly caught up by incomplete or inconsistent data.

"DHS IS TELLING OFFICERS TO LIE TO DO IT. THIS NEW DHS INITIATIVE IS NOTHING MORE THAN AN UNLAWFUL ORDER BY THE GOVERNMENT TO SILENCE THE VOICES OF AMERICANS."

That's Schumer's characterization of the initiative. Padilla was similarly blunt, saying the whistleblower's account "outlines shocking allegations of unlawful and unethical conduct" and demanding that DHS Secretary Markwayne Mullin and USCIS Director Joseph B. Edlow halt the program and report to Congress on its activities, according to the senators' joint statement.

DHS pushes back

A DHS spokesperson defended the effort, saying the department "accessed publicly available data from states' voter rolls and cross referenced them with known aliens in our systems," adding, "It's not rocket science; it's an easy step to secure our elections." The spokesperson also rejected claims the investigations were rushed, telling reporters the work is "conducted diligently and professionally," according to NPR member station coverage of the DHS response.

The dispute over methodology matters beyond the paperwork: previous state and federal audits have repeatedly found confirmed cases of noncitizen voting to be exceedingly rare, even as the Trump administration has expanded voter-roll reviews across multiple agencies in the run-up to November's midterms. CNN reported that officers were given only weeks to sift through the records of thousands of people, using voter-file data that USCIS's own staff have described as incomplete.

What happens next is now a congressional pressure campaign rather than a courtroom fight — at least for now. Padilla and Schumer are pushing for DHS to pause the initiative and turn over records to the Senate; DHS has given no indication it plans to do either. With early voting in several midterm states set to begin within weeks, the fight over how — and how fast — the government is vetting voter rolls is likely to intensify.
