Inside the Federal Push to Build America's First National Voter Database — and the States Fighting Back

On March 31, 2026, President Donald Trump signed an executive order titled "Ensuring Citizen Verification and Integrity in Federal Elections," directing the Department of Homeland Security to create "state citizenship lists" from federal databases — the most aggressive step yet in a campaign to build what critics call an unauthorized national voter registry [1][2]. The order followed months of Justice Department lawsuits against states that refused to surrender their voter rolls, a data-sharing agreement between DOJ and DHS that prompted a key privacy officer's resignation, and an expanding web of legal challenges that has already produced multiple federal court defeats for the administration [3][4].

The result is the largest federal-state conflict over voter data in American history, one that will shape who can vote in the November 2026 midterm elections.

What the Administration Is Building

The administration's effort operates on two tracks. The first, launched in mid-2025, involves the DOJ's Civil Rights Division sending requests to at least 48 states demanding their complete voter registration lists — including names, addresses, dates of birth, driver's license numbers, and partial Social Security numbers [5][6]. The stated justification is Section 8 of the National Voter Registration Act (NVRA), which requires states to maintain accurate voter rolls and allows the Attorney General to bring enforcement actions [7].

The second track is the March 2026 executive order, which directs DHS, working with the Social Security Administration, to compile lists of citizens eligible to vote in each state using immigration records, naturalization data, and Social Security files [1][2]. DHS has been upgrading its Systematic Alien Verification for Entitlements (SAVE) database — originally designed to verify eligibility for government benefits — into a tool that state and county election officials can use to check the citizenship status of their entire voter lists [8]. The integration of SAVE with voter registration data has never existed before at this scale.

The executive order also instructs the U.S. Postal Service to send mail ballots only to voters verified through this new system, a provision that has drawn immediate legal challenges from states that rely heavily on vote-by-mail, including Oregon, Arizona, and California [9][10].

Twelve states — Alaska, Arkansas, Indiana, Louisiana, Mississippi, Nebraska, Ohio, Oklahoma, South Dakota, Tennessee, Texas, and Wyoming — have fully complied, providing the DOJ with sensitive personal information including driver's license and Social Security numbers [5]. Five additional states provided only publicly available voter information such as names, addresses, and party affiliation, while withholding more sensitive data [5].

The remaining 31 states and the District of Columbia refused to provide any voter data [5]. The DOJ has responded by filing federal lawsuits against 30 states and DC, seeking court orders to compel disclosure [6][7].

Within minutes of the executive order signing, officials in Arizona, California, and Oregon announced they would sue the administration [11]. Time reported that states including Maine and Nevada issued formal rebukes [10].

Court Defeats and the Path to the Supreme Court

The administration's legal campaign has met significant resistance in federal courts. Judges in at least four states have dismissed the DOJ's voter data lawsuits:

• California (January 15, 2026): The court held that the DOJ's demands violated federal privacy law and dismissed all claims [12].
• Georgia (January 23, 2026): Dismissed on jurisdictional grounds — the DOJ filed in the wrong district [13].
• Oregon (January 26, 2026): The court dismissed the case after a supplemental hearing that addressed Attorney General Pam Bondi's demand for Minnesota's voter data as a condition for ICE leaving the state [14].
• Michigan (February 10, 2026): The court dismissed all claims [15].

In several of these rulings, judges found that the DOJ failed to provide an adequate "statement of the basis and purpose" for its requests, concluding that the department's stated rationale was an invalid use of the Civil Rights Act [14][15].

The DOJ has appealed all four dismissals and sought expedited review of the Michigan case in the Sixth Circuit, meaning appellate decisions could arrive before the November midterms [15]. The Michigan case is viewed by election law experts as the most likely vehicle to reach the Supreme Court [15].

The Legal Battle: Commandeering and Constitutional Authority

Election law scholars have raised several constitutional objections. The most prominent is the anti-commandeering doctrine, rooted in the Tenth Amendment, which holds that the federal government cannot force state officials to implement or enforce federal programs. The Supreme Court established this principle in New York v. United States (1992) and Printz v. United States (1997) [16][17].

Legal analysts at Just Security have argued that the executive order is "unconstitutional on its face" because the Constitution assigns the power to set the "Times, Places and Manner" of federal elections to state legislatures and Congress — not the executive branch [18]. The Elections Clause (Article I, Section 4) grants Congress, not the president, the authority to override state election rules.

"Directing state election officials to receive and implement federal voter lists constitutes federal commandeering of state officials," wrote scholars at the Marquette University Law School, characterizing the administration's approach as "federalism by extortion" [17].

The administration cites the NVRA and the Help America Vote Act (HAVA) as statutory authority, arguing that accurate voter rolls require federal coordination. Supporters, including the Heritage Foundation, contend that the federal government has both the legal authority and the practical necessity to ensure that only citizens appear on voter rolls [19].

The Kobach Commission Precedent

The current effort is not the administration's first attempt at building a national voter database. In May 2017, Trump established the Presidential Advisory Commission on Election Integrity, chaired by Vice President Mike Pence with Kansas Secretary of State Kris Kobach as its operational leader [20]. The commission requested personal voter information from all 50 states; 44 states and DC declined to supply some or all of the requested data [20][21].

The commission disbanded in January 2018 without making any findings of voter fraud, after a federal court ordered it to share its working documents with its own Democratic members [20][22]. Press Secretary Sarah Huckabee Sanders cited state noncompliance as the reason for its dissolution [22].

What has changed since 2017 is the enforcement mechanism. The Kobach Commission relied on voluntary compliance and had no legal authority to compel data transfers. The current administration is using DOJ litigation under the NVRA — a statute designed to protect voting rights — to force compliance through federal courts [7]. It has also introduced financial coercion: Attorney General Bondi's demand that Minnesota share voter rolls and welfare data as a condition for pulling ICE agents from the state represents a form of leverage that the Kobach Commission never attempted [23][24].

The Administration's Case: Noncitizen Voting

The administration justifies the database as necessary to combat noncitizen voting, which Trump has repeatedly called a widespread problem. The evidence, however, is contested.

State-level investigations have consistently found that initial claims of noncitizen voter registrations shrink dramatically under scrutiny. Iowa's Secretary of State initially flagged 2,176 potential noncitizens on voter rolls in 2025, a number that fell to 277 after investigation — roughly one-hundredth of one percent of registered voters — with 35 individuals who allegedly cast ballots [25]. Michigan's audit found 16 noncitizens who voted in the 2024 general election, representing 0.00028% of votes cast [25]. Texas flagged 2,700 potential noncitizens out of more than 18 million registered voters [25].

The Center for Election Innovation & Research concluded that "in every examined case, when claims about large numbers of noncitizens on voting rolls are subject to scrutiny and properly investigated, the number of alleged instances falls drastically" [25].

Supporters of the database argue that even small numbers of noncitizen voters undermine public confidence in elections and that existing tools are insufficient. The Heritage Foundation has called for "rehabilitating" or replacing the Electronic Registration Information Center (ERIC), the multistate voter data consortium that Republican-led states have been abandoning [19]. Nine states left ERIC between 2022 and 2023, leaving 25 states as members as of February 2026 [26][27]. Heritage and allied groups argue that ERIC's governance structure is biased and that a federal system would be more effective at identifying cross-state duplicate registrations — ERIC has identified over 13.5 million cross-state movers since 2013 [28].

Election security researchers counter that ERIC already provides the cross-state matching capability the administration claims to need, and that a federal database introduces far greater risks of error and misuse without demonstrating superior accuracy [26][28].

Who Gets Access — and Who's Watching

The question of who would access the completed database has become a central flashpoint. During a court hearing in Rhode Island, DOJ attorney Neff acknowledged that the department plans to share voter registration data with DHS so it can be run through the SAVE database to identify potential noncitizens [3][29].

The data pipeline would thus connect: state voter rolls → DOJ → DHS (via SAVE) → potentially ICE's Homeland Security Investigations for enforcement. In a March 2026 Minnesota hearing, DOJ attorney James Tucker told a judge he had no "intention to use this data to conduct immigration enforcement" [29]. But the operational reality appears different: voters flagged by SAVE as potential noncitizens are referred to ICE for investigation [29].

The Electronic Privacy Information Center (EPIC) has warned that "the DOJ is woefully unprepared to receive or protect" voter data, describing the department's data security plan as consisting of "vague gestures and empty assurances" [30]. Former DOJ attorneys have confirmed that the administration intends for the Department of Government Efficiency (DOGE) team to analyze voter registration data alongside DHS and Social Security Administration records [8].

The resignation of Kilian Kagle, the chief FOIA officer and senior privacy official for DOJ's Civil Rights Division, in early April 2026 has amplified concerns. EPIC's Davisson described it as part of an "exodus" of privacy and data security professionals across federal agencies [4]. No public audit logging, data retention, or breach notification policies have been disclosed for the voter data already collected [30].

Civil Rights and Suppression Risk

Civil rights organizations project significant harm to historically disenfranchised communities if the database becomes operational.

The ACLU has warned that key provisions of the executive order "could disenfranchise millions of eligible voters, particularly voters of color, women voters, naturalized citizens, voters with disabilities, voters with low incomes, and first-time voters" [31]. The organization, along with Common Cause, has filed motions to intervene as defendants in DOJ lawsuits across 14 states, including Arizona, Colorado, Georgia, Illinois, Maryland, Massachusetts, Minnesota, New Mexico, Pennsylvania, Rhode Island, and Wisconsin [32][33].

The specific risk to naturalized citizens is well-documented from prior data-matching programs. The SAVE database was not designed for voter verification and does not always reflect when individuals are naturalized after their initial immigration records are created [8][31]. American citizens born before 1978 and naturalized citizens are the populations most at risk from inaccuracies in SAVE data [31]. Smaller-scale attempts by states to use immigration data for voter verification have repeatedly produced false matches, flagging citizens as noncitizens [8].

Democracy Docket has described the administration's broader approach as a "war on naturalized citizens' right to vote," noting that the Trump administration has elevated denaturalization — the historically rare process of stripping citizenship — as a core enforcement tool [34]. Senator Alex Padilla and Senator Dick Durbin have accused the administration of planning to "seize private voter data to purge voter rolls," arguing that the DOJ's request "threatens voter privacy and could enable voter disenfranchisement" targeting naturalized citizens [35].

Common Cause president Virginia Kase Solomón stated that "if Trump and his administration succeed, many voters may either be purged from the voter rolls or be too intimidated by the threat of federal access to their information to register" [32].

What Happens Next

The legal and political battles will intensify as the 2026 midterms approach. The Sixth Circuit's expedited review of the Michigan case could produce the first appellate ruling on whether the NVRA authorizes the DOJ's data demands [15]. The executive order faces its own separate litigation track, with voting rights groups challenging both the national citizenship list provisions and the USPS mail ballot restrictions [9][31].

At the state level, the picture is fracturing. Some compliant states are providing data that is already flowing to DHS, while over 30 states are engaged in active litigation to prevent any transfers [5][6]. The administration's willingness to use ICE enforcement as leverage — as demonstrated in Minnesota — suggests the pressure on holdout states will increase [23][24].

The fundamental question is whether the federal government can compel states to surrender their voter data, route it through immigration enforcement databases, and use the results to determine who is eligible to vote — all through executive action rather than legislation. The courts will decide, but the data already shared by compliant states cannot easily be unshared. Whatever the legal outcome, the administrative infrastructure for a national voter database is being built in real time.
