The US Department of Justice (DOJ) announced on Thursday that it is suing six states for failing to produce their statewide voter registration lists after they were requested.

California, Michigan, Minnesota, New York, New Hampshire and Pennsylvania were among the states targeted by the DOJ in identical lawsuits after they did not produce details pertaining to their states’ voter registration lists when the DOJ requested them.

“Clean voter rolls are the foundation of free and fair elections,” US Attorney General Pamela Bondi said in a statement. “Every state has a responsibility to ensure that voter registration records are accurate, accessible, and secure—states that don’t fulfill that obligation will see this Department of Justice in court.”

Following a request by the DOJ for the statewide voter registration lists, each state only provided the publicly available voter registration information, rather than more detailed voter information that would include driver’s license and social security information of voter registrants.

The lawsuits are part of President Donald Trump’s Executive Order No. 14248 from March 25 that aimed to address federal guidelines, testing, and certification of voting systems in the US. The order required voting systems to “provide a voter-verifiable paper record to prevent fraud or mistake” and requested all states help determine whether individuals are eligible to register to vote. The DOJ was charged with taking “appropriate action” against states that failed to comply.

Pennsylvania Secretary Al Schmidt, a Republican, said in a statement issued in August that state laws did not permit compliance with the request.

“This request, and reported efforts to collect broad data on millions of Americans, represent a concerning attempt to expand the federal government’s role in our country’s electoral process,” Schmidt said.

The lawsuits, identical in nature but filed in the federal districts of each respective state, argued Congress charges the Attorney General’s office to enforce two laws that require states to comply with the DOJ’s requests for states’ voter registration information: the National Voter Registration Act (NVRA), which spells out voter registration requirements, including that states offer voter registration opportunities in motor vehicle agencies and that there be opportunities to vote by mail; and the Help America Vote Act (HAVA), which creates a new federal agency to act as a clearinghouse for election administration information, provides funds to states toward improving election administration and voting systems, and creates a set of minimum standards for states to abide by for election administration.
