Pennsylvania Attorney General Josh Shapiro announced Thursday that his office is suing Senate Republicans in order to stop them from subpoenaing the personal information of voters. The lawsuit alleges that their efforts to subpoena the personal information of nine million Pennsylvanians invades Pennsylvanians’ right to informational privacy under the Pennsylvania Constitution.

As part of a “forensic investigation” of the 2020 election, Senators Chris Dush, Jake Corman, and the Senate Intergovernmental Operations Committee requested the name, date of birth, partial Social Security number, and driver’s license number for every Pennsylvanian who voted in the 2020 presidential election. They also wanted to know the method of voting and when each registered voter cast a ballot. As a reason for that request, they cited concerns about the integrity of the election.

In response, the Office of the Attorney General filed a lawsuit Thursday in the Commonwealth Court of Pennsylvania on behalf of the Commonwealth of Pennsylvania, Department of State, and Acting Secretary Veronica Degraffenreid.

The lawsuit argues that the committee’s concerns about alleged integrity issues during the election are based on false, partisan narratives. Additionally, the lawsuit argues that providing the personal information of so many voters is a great risk, especially because the committee did not implement needed security protocols to protect the information from third-party companies.

Shapiro stated: “Giving this data away would compromise the privacy of every Pennsylvania voter—that violates Pennsylvanians’ constitutional rights. By trying to pry into everyone’s drivers license numbers and social security numbers they have gone too far.”

In Pennsylvania, there have been challenges to the 2020 presidential election and to the state’s voting rules and requirements. The US Supreme Court dismissed the final challenge to the 2020 presidential election from Pennsylvania in April. In early September, 14 Republican lawmakers filed a complaint challenging Act 77, which established universal mail-in voting in the Commonwealth of Pennsylvania in October 2019, as unconstitutional.
