"Numerous states are refusing to give information to the very distinguished VOTER FRAUD PANEL. What are they trying to hide," Trump wrote.
The Trump administration's Presidential Advisory Commission on Election Integrity sent all 50 states a letter Wednesday requesting data from the their voting rolls, including the full names of registered voters, dates of birth, party registration, last four digits of Social Security numbers and voting history.
Some state officials also expressed concerns that the request was evidence of an agenda by the Trump White House and dismissed it as politically motivated posturing.
"I have no intention of honoring this request," Virginia Gov. Terry McAuliffe, a Democrat, said in a statement. "Virginia conducts fair, honest, and democratic elections, and there is no evidence of significant voter fraud in Virginia. This entire commission is based on the specious and false notion that there was widespread voter fraud last November.

Mississippi Secretary of State Delbert Hosemann, a Republican, said of Kobach's letter: "My reply would be: They can go jump in the Gulf of Mexico, and Mississippi is a great state to launch from. Mississippi residents should celebrate Independence Day and our state's right to protect the privacy of our citizens by conducting our own electoral processes."
Connecticut Secretary of State Denise Merrill, a Democrat, said she would share information that is publicly available "in the spirit of transparency" while also protecting private voter information. But she also criticized Kobach's track record and expressed concern in an ulterior motive.
"In the same spirit of transparency, we will request that the commission share any memos, meeting minutes or additional information, as state officials have not been told precisely what the commission is looking for," Merrill said. "This lack of openness is all the more concerning, considering that the vice chair of the commission, Kris Kobach, has a lengthy record of illegally disenfranchising eligible voters in Kansas."
Kobach, who is Kansas' secretary of state, backed a national cross-referencing system to allow states to check their voter rolls for overlaps, which drew criticisms that the system was too prone to allowing legitimate voters to be purged from voting systems.
Kobach also fought unsuccessfully in court for the ability to require verification of citizenship on voter registration forms.
Senate Majority Leader Mitch McConnell has said he wants state governments to perform the task of wiping voters who have died or moved away off their voting rolls.
"There's no evidence that it occurred in such a significant number that would have changed the presidential election," he added. "And I don't think we ought to spend any federal
