The U.S. Department of Justice has filed a lawsuit against Colorado Secretary of State Jena Griswold after she refused to provide the agency with certain voter information.

Last week, the DOJ’s Civil Rights Division asked Griswold’s office to provide unredacted voter data, including full names, dates of birth, residential addresses, and driver’s license numbers.

Federal authorities have sought voter data from more than 20 states, saying it’s part of project to ensure election security.

The DOJ lawsuit, filed in U.S. District Court in Denver, alleges that Griswold violated the federal Civil Rights Act by refusing to provide the records.

“This proceeding arises from the Attorney General’s investigation into Colorado compliance with federal election law,” the lawsuit against Griswold said.

Griswold has insisted that the does not have a legal right to the information it is seeking.

“The DOJ can take a hike,” Griswold earlier said. “Colorado will not help (President) Donald Trump undermine our elections and hurt the American people.”

This isn’t the first time the DOJ has made such requests.

In May, the department requested copies of voter registration files from at least 40 states. Two of those states – Indiana and Wyoming – provided complete and unredacted voter registration lists. The majority, including Colorado, refused, citing privacy and security worries. They sent publicly available and redacted files.  

Last month, Griswold and nine other secretaries of state wrote a letter to the DOJ and the Department of Homeland Security requesting more information about why the agencies are requesting voter data and if they plan to share it with the Department of Homeland Security.

The officials also alleged that DOJ and DHS staff have shared “misleading and, at times, contradictory” information with elections officials regarding voter data collection. They added that transmitting the information to another federal agency raises “serious Privacy Act concerns and risks improper dissemination of and access to sensitive voter data.”

Griswold’s office said neither the DOJ nor DHS has responded to the letter.

The lawsuit against Griswold is one of 14 suits filed against states that have refused to share voter data and other election information, including New Mexico, Vermont, and Washington.

“We will not hand over Coloradans’ sensitive voting information to Donald Trump,” Griswold said in a statement following news of the lawsuit against her. “He does not have a legal right to the information. I will continue to protect our elections and democracy, and look forward to winning this case.”

Previously, the DOJ has portrayed the cases against other states as attempts to ensure the accuracy of voter lists.

“Accurate voter rolls are the cornerstone of fair and free elections, and too many states have fallen into a pattern of noncompliance with basic voter roll maintenance,” Attorney General Pam Bondi said in a news release last week. “The Department of Justice will continue filing proactive election integrity litigation until states comply with basic election safeguards.”
