Maryland AG Sues to Block ICE Detention Center Construction

Lawsuit alleges federal agencies violated environmental laws in purchasing facility near Hagerstown

Published on Feb. 23, 2026

Maryland Attorney General Anthony Brown has filed a lawsuit against the Department of Homeland Security (DHS) and Immigration and Customs Enforcement (ICE) to prevent the construction of a new immigration detention facility in Washington County. The lawsuit claims the agencies violated environmental laws by purchasing a 54-acre commercial property in Williamsport without conducting required environmental reviews or allowing public input.

Why it matters

The proposed 1,500-bed detention center has raised concerns from state lawmakers and residents about its potential impact on the local community, including environmental, public health, and safety issues. The lawsuit aims to halt the Trump administration's plans to rapidly expand immigration detention capacity across the country.

The details

According to the lawsuit, ICE purchased the $102.4 million facility on January 16 without performing environmental assessments or providing opportunities for public feedback as required under the National Environmental Policy Act (NEPA). The lawsuit argues the agencies violated the Administrative Procedure Act by failing to consider alternatives and provide justification for their decision. Concerns have also been raised about the detention center's impact on air quality, traffic, public health, and the potential for inhumane holding conditions and limited access to medical care.

What they’re saying

“DHS purchased this while keeping the State and the public in the dark, spending more than $100 million in federal taxpayer dollars without performing the required environmental review and without giving Maryland or Marylanders any voice in the process. We will not allow this Administration to treat laws like suggestions and threaten our people or their communities.”
