Federal authorities this week teased a “separate batch” of 17,000 potential noncitizen voters in their federal court challenge to California’s handling of alleged voter fraud.
In response, Los Angeles County officials questioned the accuracy of the government’s earlier list of 20,000 alleged noncitizen voters — saying a preliminary review of a subset of those voters found evidence that nearly 40% were born in the U.S.
The claims came in filings shedding new light on the unprecedented Homeland Security inquiry into California’s voter rolls just weeks before the Nov. 3 election.
On Monday, Nicolas Bartell, a Homeland Security official, wrote in a sworn affidavit that — in addition to developing the disputed list of 20,000 “likely noncitizen” voters at the heart of the litigation — his agency has also developed a “separate batch of more than 17,000 voting records potentially tied to noncitizens.”
“Our review is ongoing as USCIS receives records on a rolling basis before the election date,” wrote Bartell, the associate director of the Fraud Detection and National Security Directorate at U.S. Citizenship and Immigration Services.
On Tuesday, Monica Flores, a top official in the L.A. County Registrar-Recorder/County Clerk’s office, wrote in an affidavit that staff members had reviewed a sample of 200 registrations from the list of 20,000 voters whom the Justice Department alleged last week were “likely noncitizens.” The office found that more than half — 112 — had been canceled or were inactive, meaning no ballot was sent to those voters.
In instances where those voters’ birthplace was “meaningfully reported, 38.9% indicate that they were born in the United States, which is strong evidence of citizenship,” Flores wrote, while 71.2% showed no record of ever voting.
Flores wrote that similarly vetting the citizenship of thousands of additional voters before the election would not only be “administratively impossible and take key personnel away from their critical election duties,” but would also “risk disenfranchising voters who are validly registered.”
Also Tuesday, Rachel Evans, an attorney in the California secretary of state’s office, wrote in an affidavit that the office since August has received and been complying with grand jury subpoenas for the detailed voter records of about 300 people.
Evans’ acknowledgment came a day after federal prosecutors charged 28 people across California with federal election-related crimes, including fraudulent voter registration and making false statements in a naturalization application, and suggests federal prosecutors are pursuing criminal cases against hundreds more.
Taken together, the filings indicate that the legal battle between the Trump administration and California over alleged fraudulent voting is only just gearing up — with no end in sight before Nov. 3 — as is the political sparring over the issue.
First Assistant U.S. Atty. Bill Essayli, the lead federal prosecutor in Los Angeles, posted to X on Tuesday that Flores’ acknowledgment that her office could not possibly vet voters’ citizenship before the election was a “massive concession,” proving the federal government’s case.
Gov. Gavin Newsom’s office said that “any credible allegation of voter fraud should be taken seriously and investigated,” but that federal officials charging just 28 people in a state with 23 million voters showed they have no evidence of widespread fraud.
“Yes, non-citizen voter registration and voting does happen in isolated instances — in California and the rest of the country alike — but it is so rare that the Trump admin is parading around town about .0001% of California voters,” Newsom’s office wrote on X.
The broader case
On Monday, Justice Department lawyers filed a request for an emergency restraining order requiring state election officials to segregate any ballots from the 20,000 voters flagged on the initial Homeland Security list until their citizenship is proved. They argued the state is violating the law — and harming the federal government — by refusing to do so.
State attorneys argued Tuesday that the federal government has no authority over California elections and seeks to violate federal law precluding voter roll purges in the 90 days before an election.
State officials wrote that the Justice Department appeared to have “individualized evidence” of noncitizenship for the 28 people it had charged, and that nothing was preventing it from working through existing “statutory channels” to block those individuals’ ballots. But they argued that it does not have evidence to back its claims against all 20,000 voters whose ballots it is seeking to sequester.
Those contentions — and Bartell’s claim of a second list of 17,000 potential noncitizen voters — only add to an already heated debate about the scope of the inquiry and its legitimacy.
In July, Homeland Security Secretary Markwayne Mullin alleged in a letter to California Secretary of State Shirley Weber that there “may be as many as 190,832 noncitizens registered to vote in California,” and demanded that the state work with federal authorities to investigate. The state asked that Homeland Security first provide more information, including about its methodology for identifying that figure.
Last week, acting Deputy Atty. Gen. Trent McCotter wrote follow-up letters to Weber and Dean Logan, head of the L.A. County registrar’s office, asserting that 20,000 “likely noncitizens” were on state rolls, and again demanding state cooperation within 48 hours to remove them. Weber balked, arguing that federal law precludes systematic roll purges within 90 days of an election to protect eligible voters.
Weber and other state officials also questioned the drop from 190,000 to 20,000, and the reliability of the federal government’s underlying data and methodology. “What happened to the 170,000? You just got those wrong?” California Atty. Gen. Rob Bonta asked.
On Monday, McCotter said the 190,000 figure was “the ceiling,” inclusive of cases that federal authorities had high, medium and low confidence in, while the 20,000 figure was “the floor,” inclusive of only high confidence cases.
Potential flaws in the list have been a major point of contention among California officials, who have pointed to substantial inaccuracies in lists elsewhere, including in Nevada, where a state review found that the 185 voters whose citizenship was questioned by the Trump administration were all citizens.
Now, it appears the federal government’s disputed list of 20,000 voters won’t be the last in California.
How voters were identified
In court filings, federal officials described purchasing California voter registration information before USCIS and Homeland Security Investigations agents worked to identify any voters who are not citizens. They said that they did so in part by comparing the state data with “third party commercial data” sets and law enforcement data sets, and that they further vetted their list by culling dead people.
Essayli pointed to those descriptions to dispel arguments that federal authorities have not provided their methodology for identifying potential noncitizens on voter rolls. He said that the federal process was robust and trustworthy and that federal authorities had compiled “overwhelming evidence of tens of thousands of ineligible voters on the state’s rolls.”
Independent election experts saw it differently.
“They admitted to using some of the same tools amateur election conspiracy theorists use, like unidentified third party software, commercial lists, and public versions of [the state’s] voter roll,” Gowri Ramachandran, an election administration expert at the Brennan Center for Justice at NYU School of Law. “These amateur data matching efforts don’t get any better merely because the Department of Justice relies on them.”
“If DOJ could prove many more cases, we would have heard about it,” Rick Hasen, director of the Safeguarding Democracy Project at UCLA School of Law, wrote in a blog post. “They’ve been on an aggressive hunt nationally for such fraud. It’s not surprising they’ve found little because it is a small problem.”
