An election commission established by President Trump has asked all 50 states to hand over detailed personal information about U.S. voters, in a move that civil rights advocates say is aimed at suppressing voter turnout. The request was made by Kris Kobach, the Kansas secretary of state and vice chair of Trump’s Presidential Advisory Commission on Election Integrity. Kobach has pushed for the strictest voter identification laws in the country and advocated for a “proof-of-citizenship” requirement at the state and federal levels. At least three states—California, Connecticut and Virginia—said they would refuse to comply with the request. In a statement, the Lawyers’ Committee for Civil Rights Under Law said, “This meritless inquisition opens the door for a misguided and ill-advised Commission to take steps to target and harass voters and could lead to purging of the voter rolls.”
