New Jersey Democratic Gov. Mikie Sherrill’s recent announcement of 6,600 ineligible voters found on the state’s rolls is only the latest in a decades-long string of cases involving noncitizens registered to vote in U.S. elections, records show.
Sherrill said that the ineligible voters were registered due to a “serious software error” in New Jersey’s Motor Vehicle System. Her announcement came within a week of a major address from President Donald Trump in which he warned that digital election interference posed a “cyber threat aimed at the very heart of our democracy.”
While New Jersey is the latest documented failure, it is not an isolated anomaly. New Jersey’s error adds to a 25-year record of state reviews, software failures and prosecutions that found noncitizens on voter rolls and, in some documented cases, casting ballots. Experts say the episodes establish a recurring vulnerability. However, due to the lack of a national standard for identifying and reporting errors, reviews are sporadic and use different methods, making it impossible to determine how widespread the problem truly is.
“It’s a major vulnerability,” Jason Snead, executive director of the conservative think tank the Honest Elections Project, told Fox News Digital. “And we have seen just within the last couple of years many states that have checked their voter rolls and found non-citizens on them … So, this is a big problem.”

According to New Jersey’s preliminary findings, fewer than 400 individuals who were improperly registered ended up voting. Sherrill said they lived all across the state and mostly lacked a party affiliation, though there were some registered as Democrats or Republicans.
Fox News Digital reached out to the New Jersey Secretary of State Division of Elections, state Attorney General Dale Caldwell and the chairs of several key legislative elections’ oversight committees for clarification on which elections the 400 ineligible voters participated in and to request details on the state’s auditing protocols. Fox News Digital did not receive a response from any of the state officials mentioned above.
Snead explained that though states are required by law to ensure their voter rolls are up-to-date and accurate, there is no uniform federal requirement for a state to disclose its findings. He said that this has led to differences across states in how the law is enforced and how errors are reported.
“There are federal requirements to maintain clean and accurate voter rolls. And of course, it is a federal crime for a noncitizen to register and to vote, but there’s no requirement that a state report how many non-citizens that they have found up to the federal government. That’s entirely a state law question,” he explained.
He argued that problems involving noncitizen voting are greater in blue states due to policies he said make it easier to cheat.

“When you look at the policies that are pushed in blue states by the left, things like automatic voter registration, giving driver’s licenses to illegal aliens, banning voter identification laws, no proof of citizenship to vote on and on and, this is the inevitable outcome of all of those policies,” said Snead, adding, “This is not the first time that we’ve seen a state with automatic voter registration add potential non-citizens to the rolls.”
After the president’s speech, Homeland Security Secretary Markwayne Mullin released a statement announcing that preliminary DHS reviews of state records found “as many as” 250,000 noncitizens registered to vote in four states: 35,152 in New Jersey, 190,832 in California, 15,903 in Nevada and 14,576 in Pennsylvania.
Fox News Digital reached out to DHS for clarification on its preliminary findings. However, DHS did not answer Fox News Digital’s questions and instead sent a statement from Mullin reiterating the number.
In the statement, Mullin emphasized to Fox News Digital that “this shouldn’t be a red or blue state issue: ONLY Americans should elect American leaders.” He added that “we’ve put these governors on notice. States must work with us to ensure free, fair, and honest elections.”
Charles Stewart III, a professor of political science specializing in elections at MIT, explained that the controlling federal law governing voter registration, the National Voter Registration Act (NVRA), is “silent on the issue of noncitizens on the roll.”
He told Fox News Digital that because “this was not an issue in the early 1990s … one of the ambiguities right now and controversies is over precisely what sort of obligations states have to audit their rolls for noncitizens.”
“This is really at the crux of the matter and two of President Trump’s executive orders. It’s the crux of the matter in the Save America Act. It is the crux to the matter in the current efforts, well, back to the executive orders and a lot of the lawsuits. And the states are pointing out, when being pressed by the federal government, that yes, it is illegal for noncitizens to vote, for sure, and states should have an obligation to make sure noncitizens are not registering, but there is no federal law that compels states to do investigations, nor is there a federal law to compel them to report.
Meanwhile, states that have published review results have reported concerning findings. Besides New Jersey, state reviews conducted since 2020 have found evidence of significant numbers of noncitizens registered to vote in Louisiana, Iowa, Michigan, Ohio and Illinois, a Fox News Digital review found.
Earlier this year, the Louisiana secretary of state said that using the federal Systematic Alien Verification for Entitlements (SAVE) database, which was rolled out by the Trump administration last year, the state identified 403 noncitizens on its voter rolls, 83 of whom had voted in elections, American Press reported.
In 2025, an audit by the Iowa secretary of state confirmed that 277 noncitizens were registered to vote and that 35 successfully voted in the 2024 election while five attempted to vote but were rejected.
