Khalif Ali, executive director of Common Cause Pennsylvania, a good-government advocacy group that works on issues related to voter access, called the subpoenas approved Wednesday a “frightening violation of voters’ privacy and an egregious abuse of power.”

“There’s no explanation about what they intend to do with the information, or why they think they need it,” he said in a statement. “They also have not announced any plans for security measures to protect the information from disclosure. … Pennsylvanians deserve to have their private information protected by the people they elected to office, not used as political fodder to appease lies told by a former president.”
