New Jersey officials revealed Tuesday that a software malfunction at the state’s Motor Vehicle Commission mistakenly placed roughly 6,600 noncitizens on the voter rolls over the course of a year. State officials said fewer than 400 of those individuals ultimately voted before the erroneous registrations were identified and removed.

According to the Murphy administration, the registration problem occurred between June 2023 and June 2024, well before Gov. Mikie Sherrill assumed office.

Officials explained that the affected applicants had visited the MVC to obtain driver’s licenses or state identification cards and had correctly indicated that they were not U.S. citizens. Despite those responses, a flaw in the agency’s voter registration system automatically added them to New Jersey’s voter database.

“Through no fault of their own, the system registered them,” Sherrill said in a statement obtained by the New Jersey Globe.

The announcement followed President Donald Trump’s prime-time address just five days earlier, during which he argued that New Jersey had a significant number of noncitizens listed as registered voters.

Trump claimed that 35,152 noncitizens appeared on New Jersey’s voter rolls and estimated that approximately 250,000 noncitizens were registered across New Jersey, California, Nevada, and Pennsylvania.

Sherrill said she first learned of the issue last week and immediately directed state officials to investigate the matter while removing every voter registration that had been improperly created during the affected timeframe.

“I also ordered the removal of any residents from our voter rolls who were erroneously added between June 2023 and June 2024,” she said. “The new MVC administrator that I appointed has begun the process of replacing the vendor responsible for administering the system.”

The software involved was administered by IDEMIA, a company that supplies digital identity and biometric services to government agencies, including the TSA PreCheck program.

Sherrill said the state has already completed the removal of the improper voter registrations.

“Our preliminary analysis shows fewer than 400 individuals who were newly registered for the first time because of the error voted,” she said. “They were registered as Democrats, Republicans, and unaffiliated voters and were scattered across the state.”

State officials have not disclosed which elections those ballots were cast in or whether any contests were affected by the votes.

The New Jersey Globe reported that the software errors occurred while Latrecia Littles-Floyd was serving as acting chief administrator of the MVC during the administration of then-Gov. Phil Murphy. The report also noted that Littles-Floyd had previously been linked to a separate MVC issue in which eligible U.S. citizens were mistakenly removed from the voter rolls and efforts to remedy that problem reportedly faced resistance.

Officials have not determined whether Littles-Floyd or other members of the Murphy administration were aware of the software defect before it became public.

“I am appalled by the reckless failures that allowed this to happen, and the lack of transparency shown by those in charge at the time,” Sherrill said. “This failure didn’t occur under my watch, but accountability starts now.”

While outlining steps to strengthen confidence in the state’s election system, Sherrill also criticized Trump’s repeated claims regarding election security.

“The difference is simple: when we find a problem, we don’t hide it, deny it, or invent conspiracies,” she said. “We investigate it, we fix it, and we tell the public. That’s what accountability and good governance look like, and that’s exactly what my administration is doing.”
