Donald Trump and Kris Kobach. Associated Press/Carolyn Kaster The Presidential Advisory Commission on Election Integrity asked all 50 US states for information on individual registered voters and plans to make that data public.

The group was formed in response to President Donald Trump's claims that nearly three million unlawful votes were cast in the 2016 presidential election, causing him to lose the popular vote. That claim was widely debunked.

As of this writing, at least 27 states have rejected the commssion's request.

US states have overwhelmingly rejected a request for sensitive voter information from the group in charge of investigating President Donald Trump's claims of voter fraud.

The bipartisan Presidential Advisory Commission on Election Integrity sent a letter to all 50 states on Wednesday requesting an overwhelming amount of information on individual registered voters.

As of Friday night, at least 27 states, including Arizona, California, Kentucky, New Mexico, New York, Oklahoma, Texas, and Wisconsin have denied the commission's request.

The bipartisan commission is led by Vice President Mike Pence and Kansas Secretary of State Kris Kobach.

The letter dated June 28 and signed by Kobach asks for registered voters' names, addresses, dates of birth, partial social security numbers, political party, a decade's worth of voter history, information on felony convictions, and whether they have registered in more than one state.

The letter was followed by a separate one from the US Justice Department, which asked states to reveal how they maintain their voter rolls. The commission said all voter data submitted by the states would be made public.

The group was formed in response to Trump's claims that nearly three million unlawful votes were cast in the 2016 presidential election, causing him to lose the popular vote. He first made the claim in November and has repeated it many times since. That claim has been widely debunked.

Experts say they are concerned about the voter-fraud commission's activities. Some said the request appeared to be politically motivated, ProPublica reported on Thursday night. One expert, according to reporter Jessica Huseman, was especially skeptical of Kobach, who has spent years focusing on voter fraud in his current role as Kansas' secretary of state. Dale Ho, director of the American Civil Liberties Union's Voting Rights Project, said of Kobach:

"I have every reason to think that given the shoddy work that Mr. Kobach has done in this area in the past that this is going to be yet another boondoggle and a propaganda tool that tries to inflate the problem of double registration beyond what it actually is."

Vanita Gupta, head of the Leadership Conference on Civil and Human Rights, torched the commission Thursday night: "Pence and Kobach are laying the groundwork for voter suppression, plain & simple," Gupta said.

How US states are responding

Election officials and lawmakers from at least five states called out Kobach's request.

California Secretary of State Alex Padilla said it is his duty to ensure election integrity and protect voters' privacy. "I will not provide sensitive voter information to a commission that has already inaccurately passed judgment that millions of Californians voted illegally," a statement from Padilla said.

Kentucky Secretary of State Alison Grimes also pushed back, saying "I do not intend to release Kentuckians' sensitive personal data to the fed. gov't." Grimes also offered a sharp rebuke of Trump in her statement, calling the president's voter-fraud claims a "lie."

Denise Merrill, Connecticut's secretary of state, said she would provide "publicly available information" to the commission, but sharply criticized Kobach, who she said "has a lengthy record of illegally disenfranchising eligible voters in Kansas." Given that history, Merrill said, "we find it very difficult to have confidence in the work of this Commission."

Virginia Gov. Terry McAuliffe said, "I have no intention of honoring this request."

Massachusetts Secretary of State William Galvin told Commonwealth Magazine, "They’re not going to get it. It's not a public record."

Mississippi Secretary of State Delbert Hosemann released a statement on Friday that told the Presidential Advisory Commission to "go jump in the Gulf of Mexico" and that Mississippi residents had a "right to protect the privacy of our citizens by conducting our own electoral processes."

Rhode Island Secretary of State Nellie Gorbea called Kobach's authority "deeply troubling" and criticized his credentials in her statement: "Secretary Kobach was fined for misleading the courts in his own state of Kansas, where his attempts to disenfranchise Kansas voters have been overthrown by the courts."

Pennsylvania Gov. Tom Wolf called the request "problematic for several reasons," and said he held "serious reservations about the true intentions of this effort in light of the false statements this administration has made regarding voting integrity."

The Presidential Advisory Commission on Election Integrity will hold its first meeting in Washington D.C. on July 19, a statement from Pence's office said.
