The administration of Minnesota Gov. Tim Walz, the Democratic vice presidential nominee, has not explained how noncitizens made it onto the state's voter rolls, according to the Republican National Committee (RNC) and the Minnesota GOP, which penned a letter to the state's Department of Public Safety.

Kevin Cline, election integrity counsel for the Republican National Committee, and David Hann, chairman of the Minnesota Republican Party, first wrote to the Walz administration last month flagging how a noncitizen, legally living in the state and fearful of jeopardizing his status, came forward to report receiving a primary ballot without having registered to vote. 

Minnesota Department of Public Safety Commissioner Bob Jacobson wrote back to Cline and Hann earlier this week. 

His letter explained that the Department of Public Safety Driver and Vehicle Services Division (DVS) "takes many steps to ensure that only U.S. citizens’ information is forwarded to the Office of the Secretary of State." That includes reviewing only a list of certain documents that qualify as proof of citizenship to determine if an applicant is a U.S. citizen. Procedures include a second review upon issuance of the applicant’s documents to verify their classification in the system.

If DVS finds a document has been classified incorrectly as valid proof of citizenship, DVS fixes the classification and does not send the record to the Office of the Secretary of State for automatic voter registration, Jacobson wrote. He added that DVS is also conducting "a thorough, manual review" of all records that have been identified as eligible for AVR since the law went into effect in 2023 "to ensure a fair and secure election this fall."

This response did not satisfy Cline nor Hann, who noted in a new letter sent Thursday how Walz in March 2023 signed a bill into law allowing illegal noncitizens to receive driver’s licenses, also known as "Driver License for All." Less than two months after signing that bill into law, Walz signed the "Democracy for the People Act," permitting automatic voter registration through DVS, Cline and Hann said. 

"While we appreciate your explanation of how the Driver and Vehicle Services Division ("DVS") is supposed to function to ensure each applicant is a U.S. citizen, your response failed to explain how noncitizens made it through that process and ultimately made it onto Minnesota’s voter rolls," Cline and Hann wrote Thursday, according to the letter obtained by Fox News Digital. 

"This is no hypothetical; lawfully present noncitizens were registered to vote through your department, and Minnesota voters deserve transparency from your department to understand how this failure occurred and how it is being addressed.

"This issue is especially concerning since the chain of events leading to implementation of Minnesota’s AVR system, put in place by Governor and Vice-Presidential Candidate Tim Walz, gives the impression it was put in place to facilitate registration of noncitizens," the letter says. "Minnesota’s voter registration system is clearly vulnerable to illegal voter registrations in its current form." 

Cline and Hann said it is "worrisome that your department is only now conducting a review of voter records identified as eligible for automatic voter registration ('AVR').

"This type of review should have been completed multiple times on a consistent schedule since AVR’s implementation," they told Jacobson. "That your department is only now beginning the review process suggests it is being done because our previous letter exposed the flaws in the AVR system and highlighted noncitizens on the rolls." 

Fox News Digital reached out to the Minnesota Department of Public Safety for comment, but it did not immediately respond.

Cline and Hann demanded Jacobson provide "full and in-depth answers" as to "when were the citizenship checks outlined in your September 3, 2024, letter put into place," "when will your ‘thorough, manual review’ begin, what will that review consist of, and when will it be completed," and "will you share the results of this manual review with the public?"

The letter also seeks details on how Jacobson has been reporting to the OSS under 201.145, including how often a report is sent to the secretary of state, how many reports have been sent since the implementation of AVR and whether those reports include noncitizens who are not lawfully present in Minnesota. Jacobson was asked if he ever compared the reported individuals under 201.145 against his own AVR records, how many noncitizens have been issued a driver’s license and were also sent to OSS since the implementation of AVR and how many individuals have been sent to the secretary of state since the implementation of AVR.

"Has there been any pressure from the Governor’s Office or elsewhere to fast-track the registration process?" Cline and Hann asked.

"Minnesota voters should not have their votes diluted because your department failed to filter out noncitizens from the automatic voter registration system," they concluded. "Mistakes have clearly been made in the design and/or implementation of the AVR system, but it is not too late to provide transparency and to address the issues before the election this November."
