Homeland Security Investigations has begun a coordinated voter-fraud enforcement surge across nine states, deploying agents for field interviews and prosecutorial reviews from September 2 through mid-October, according to the Department of Homeland Security. The initiative, run through HSI’s parent agency, Immigration and Customs Enforcement, targets Washington, Wisconsin, Missouri, Georgia, California, Pennsylvania, Nevada, New York and Connecticut, marking one of the most geographically expansive federal voter-fraud pushes of the 2026 election cycle.
What the Surge Involves
HSI field offices in the nine states are conducting interviews and reviewing potential prosecutions tied to allegations of noncitizen voting and other registration irregularities, according to a DHS spokesperson who said the agency “is actively rooting out and investigating election fraud wherever it can be found.” The operation runs alongside the department’s ongoing use of its SAVE database, which DHS says has flagged more than 24,000 cases of potential noncitizen registration since April 2025.
The Cases DHS Is Citing
Officials point to a handful of prosecutions as justification for the expanded effort, including a Mauritanian national charged with voting illegally in seven federal elections dating back to 2008 and a Colombian national sentenced to three years in prison for identity theft carried out to cast a ballot. DHS has also cited a Oklahoma City official, Shonda Lou Barnes, arrested on voter fraud charges, along with New Jersey’s discovery of roughly 6,600 noncitizens on its voter rolls between 2023 and 2024, some of whom the state says voted in federal races.
Why These Nine States
The states selected span a mix of competitive House districts and states where DHS says SAVE database matches have been most numerous, including California, which the department says has nearly 95,000 deceased voters still listed on its rolls along with tens of thousands of duplicate registrations. Georgia, Pennsylvania and Nevada are among the most closely watched midterm battlegrounds, while Washington, Wisconsin, Missouri, New York and Connecticut round out a list that DHS says reflects where investigators found the strongest indications of irregularities warranting field follow-up.
Pushback From Election Officials and Editorial Boards
Critics have questioned both the scale and the timing of the surge. The St. Louis Post-Dispatch’s editorial board argued there is “zero evidence” of meaningful noncitizen voting affecting election outcomes, and voting rights groups have warned that sending federal immigration agents to conduct in-person interviews with registered voters just weeks before the midterms risks intimidating eligible voters, particularly in immigrant communities, regardless of whether any wrongdoing is ultimately found.
How This Fits a Larger Federal Push
The HSI surge is the latest expansion of a Trump administration effort to use federal law enforcement and immigration authorities in election administration matters traditionally left to states, following the Justice Department’s demands for state voter rolls and DHS’s push to expand SAVE database access for state election officials nationwide. Supporters of the initiative argue it is a necessary anti-fraud measure given the volume of flagged cases; opponents counter that the raw number of SAVE matches includes many false positives and does not by itself prove any voter knowingly cast an illegal ballot.
What to Watch
With the surge scheduled to run through mid-October, any prosecutions or high-profile detentions connected to the initiative are likely to become flashpoints in competitive House races in Georgia, Pennsylvania and Nevada. Election officials in the nine affected states say they are watching closely for signs the interviews are reaching lawfully registered voters, while DHS has signaled it may extend or expand the program if it produces additional charges before Election Day.
