The U.S. Justice Department is suing four more states as part of its effort to collect detailed voting data and other election information across the country.

The department filed federal lawsuits against Colorado, Hawaii, Massachusetts and Nevada on Thursday for “failing to produce statewide voter registration lists upon request.” So far, 18 states have been sued, along with Fulton County in Georgia, which was sued for records related to the 2020 election.

The Trump administration has characterized the lawsuits as part of an effort to ensure the security of elections, and the Justice Department says the states are violating federal law by refusing to provide the voter lists and information about ineligible voters. The lawsuits have raised concerns among some Democratic officials and others who question exactly how the data will be used, and whether the department will follow privacy laws to protect the information. Some of the data sought includes names, dates of birth, residential addresses, driver’s license numbers and partial Social Security numbers.

Massachusetts’ top election official, Secretary of the Commonwealth Bill Galvin, blasted the suit.

“This lawsuit is simply another example of the Trump Department of Justice’s campaign to intimidate states into handing over the personal information of their voters to the federal government,” Galvin wrote in a statement. “DOJ has provided no meaningful justification for needing access to every Massachusetts voter’s personally identifiable information.

“I have absolutely no intention of handing over the names, addresses, dates of birth, political party affiliation, phone numbers, driver’s license numbers, and social security numbers of our voters to an administration that has demonstrated a pattern of using citizens’ private information to go on outrageous fishing expeditions in an attempt to settle petty grievances,” he added.

Massachusetts Attorney General Andrea Joy Campbell also fired back against the Trump administration, writing in a statement: “The privacy of Massachusetts voters is not up for negotiation. My office will work with Secretary Galvin to vigorously defend against the Trump Administration’s attempt to misuse voters’ personal information as fuel for its cruel and harmful agenda.”

“States have the statutory duty to preserve and protect their constituents from vote dilution,” Assistant Attorney General Harmeet K. Dhillon of the Justice Department’s Civil Rights Division said in a press release. “At this Department of Justice, we will not permit states to jeopardize the integrity and effectiveness of elections by refusing to abide by our federal elections laws. If states will not fulfill their duty to protect the integrity of the ballot, we will.”

Colorado Secretary of State Jena Griswold, a Democrat, said her office declined to provide unredacted voter data.

“We will not hand over Coloradans’ sensitive voting information to Donald Trump. He does not have a legal right to the information,” Griswold said Thursday after the lawsuit was filed. “I will continue to protect our elections and democracy, and look forward to winning this case.”

In a Sept. 22 letter to the Justice Department, Hawaii Deputy Solicitor General Thomas Hughes said state law requires that all personal information required on a voter registration district other than a voter’s full name, voting district or precinct and voter status, must be kept confidential. Hughes also said the federal law cited by the Justice Department doesn’t require states to turn over electronic registration lists, nor does it require states to turn over “uniquely or highly sensitive personal information” about voters.

An Associated Press tally found that the Justice Department has asked at least 26 states for voter registration rolls in recent months, and in many cases asked states for information on how they maintain their voter rolls. Other states being sued by the Justice Department include California, Michigan, Minnesota, New York, New Hampshire, Pennsylvania, Delaware, Maryland, New Mexico, Rhode Island, Vermont and Washington.

The bipartisan Wisconsin Elections Commission voted 5-1 on Thursday against turning over unredacted voter information to the Trump administration. The lone dissenter was Republican commissioner Robert Spindell, who warned that rejecting the request would invite a lawsuit. But other commissioners said it would be illegal under Wisconsin law to provide the voter roll information which includes the full names, dates of birth, residential addresses and driver’s license numbers of voters.
