FOIA Request Regarding DHS "Unmasking" Subpoenas

The American Civil Liberties Union of Pennsylvania has filed a complaint in the federal district court for the Eastern District of Pennsylvania under the Freedom Of Information Act (FOIA) to obtain more information about the Department of Homeland Security’s (DHS) use of administrative subpoenas to unmask the identities of people online and intimidate individuals who are critical of the federal government. ACLU-PA has represented two clients who have been targets of DHS subpoenas. In both cases, DHS ended its investigations once they were challenged in court. In February of this year, the ACLU of Pennsylvania submitted a request to ICE under the Freedom of Information Act, seeking records of "unmasking" subpoenas from 2024 to the present. ICE did not respond to this request, nor did the agency confirm receipt or request an extension. Our case states that ICE has a statutory obligation under FOIA to respond to our request and asks the court to order ICE to immediately make a complete search for all responsive records and fulfill our request.

United States v. Pennsylvania, et al.

The ACLU of Pennsylvania, the Public Interest Law Center, and ACLU’s Voting Rights Project have filed a motion to intervene in a federal lawsuit over the federal government’s demand that Pennsylvania turn over its entire voter registration rolls, including with voters’ sensitive personal data such as drivers’ license numbers and partial social security numbers. The motion to intervene was filed on behalf of seven Pennsylvania voters, many of whom were the target of baseless mass challenges to their mail ballots during the 2024 election cycle that resulted from faulty data-matching techniques. The voters’ experiences have heightened their concerns about the privacy of their voting data. Other plaintiffs are two non-partisan, good government organizations dedicated to voter engagement: the League of Women Voters of Pennsylvania and Common Cause. If intervention is granted, the civil rights groups will seek to prevent the federal government from forcing Pennsylvania to turn over the entirety of its voter registration database and to protect sensitive data within the voter rolls.
