Democratic lawmakers have conceded that a voter registration error in New Jersey was a "horrible" failure requiring accountability, but they have pushed back against claims that the incident suggests widespread election fraud.

New Jersey Gov. Mikie Sherrill stated Tuesday that a "serious software error" within the state's Motor Vehicle System mistakenly registered approximately 6,600 noncitizens. The company providing identity-related security services has denied any wrongdoing.

"In New Jersey, we absolutely need to have accountability for what happened," Sen. Andy Kim, D-N.J., told Fox News Digital. "It was just horrible. There was a big problem with that computer problem that they had. We need to try to address that going forward."

Kim suggested that states require better tools to maintain accurate voter rolls, rather than relying solely on federal databases. "The main thing is making sure states have what they need," he said. "I don't trust the idea that we're just going to mesh it with some DHS database. That's where a lot of the problems come in, but we should all be making sure we're looking out for election integrity."

Sherrill announced that she initiated an investigation and that the state's Division of Elections is in the process of removing ineligible voters from the rolls. She indicated that fewer than 400 of those improperly registered cast ballots.

Kim also emphasized the importance of improving election technology and maintaining paper trails.

Sen. Brian Schatz, D-Hawaii, stated that state and county officials must ensure that "only those who are eligible to vote, vote."

Rep. Ritchie Torres, D-N.Y., dismissed former President Donald Trump's assertions of widespread election fraud as "a figment of his imagination," asserting, "There's no evidence for it, and I'm not going to validate his false narratives."

Sen. Raphael Warnock, D-Ga., acknowledged that accountability is necessary but characterized noncitizen voting as "extremely rare." He added, "I have always said that people should have to prove that they are who they say they are before they vote, and we have systems in place to ensure that happens, which is why noncitizen voting remains extremely rare."

Sen. Tim Kaine, D-Va., called the error "not acceptable" and pointed to Virginia's election processes, including voter ID requirements and audits, stating they have never revealed a noncitizen voting issue.

Sen. Tammy Baldwin, D-Wis., praised Sherrill for her transparency and advocated for continuous review of election software.

Rep. Seth Magaziner, D-R.I., expressed support for a straightforward voter ID law but opposed a recent House GOP bill, which he argued included extraneous provisions beyond a basic ID requirement. "If they put up a simple voter ID bill for an up-or-down vote without any of the other bulls--- in it, I would vote for it," Magaziner said. "I think a lot of people on both sides would, too. But they keep adding other stuff, like gutting mail ballots, and that was the problem with yesterday's bill."
