Sen. Andy Kim questions nominee about proposed Roxbury ICE facility

Why It Matters

New Jersey faces a significant expansion of federal immigration detention infrastructure with the Department of Homeland Security’s purchase of a 470,000-square-foot warehouse in Roxbury, Morris County. The proposed facility would fundamentally alter the township’s capacity to manage federal operations, potentially straining local law enforcement, public services, and municipal finances. During a Senate confirmation hearing, U.S. Senator Andy Kim pressed the nominee for DHS secretary on whether the federal government has properly consulted with local communities before establishing large-scale detention centers. The outcome could set precedent for how federal agencies coordinate with municipalities on infrastructure projects with significant community impact.

What Happened

On March 18, 2026, Senator Kim, a New Jersey Democrat, questioned Senator Markwayne Mullin during Mullin’s confirmation hearing before the Committee on Homeland Security and Governmental Affairs. Mullin, a Republican from Oklahoma, is President Trump’s nominee to serve as the next secretary of the Department of Homeland Security.

Kim focused the exchange on DHS’s acquisition of a Roxbury warehouse intended to house over 1,500 immigrant detainees. The senator highlighted that local officials, including Roxbury’s mayor and law enforcement, were never consulted about the purchase or the facility’s operation. Kim noted that Immigration and Customs Enforcement (ICE) did not conduct any coordination meetings with municipal leaders before the acquisition.

During questioning, Kim emphasized the scale of the operation relative to Roxbury’s size and resources. He pointed out that the facility would represent approximately 10 percent of the township’s 22,000-person population when accounting for both detainees and staff. Kim also stressed that Roxbury’s municipal infrastructure—comprising 42 police officers and a volunteer fire department—was insufficient to manage the demands of a facility this large.

Mullin acknowledged several operational concerns raised by Kim, including the removal of the privately owned warehouse from local tax rolls and potential strain on water and waste systems. Mullin committed to visiting Roxbury personally if confirmed to assess the facility and community concerns. He suggested that if the Trump administration had specific justification for selecting Roxbury, he would share that rationale with Kim, but indicated willingness to develop “better partnerships” with local stakeholders moving forward.

By The Numbers

The proposed Roxbury detention facility spans 470,000 square feet, making it the largest migrant jail in New Jersey. The warehouse would house over 1,500 detainees—a capacity equivalent to five times the combined detention population currently held across the state’s two existing facilities. Roxbury’s total population stands at 22,000 residents, meaning the detainee and staff population would constitute approximately 10 percent of the township. The township maintains a police force of 42 officers and operates a volunteer fire department. New Jersey currently operates two privately owned detention centers: Elizabeth Detention Center with roughly 300-person capacity and Delaney Hall in Newark, representing existing federal immigration detention infrastructure in the state.

Zoom Out

The Roxbury facility represents a significant expansion of federal detention capacity in the Northeast amid broader Trump administration immigration enforcement priorities. New Jersey, as a densely populated state with major transportation corridors, has historically absorbed substantial federal immigration detention operations. However, the scale of this single facility exceeds existing operations by a substantial margin, reflecting a strategic shift toward consolidating detention in larger, centralized locations rather than distributing capacity across multiple smaller facilities.

Similar controversies have emerged in other states when DHS has established detention facilities without robust community engagement. The tension between federal immigration enforcement mandates and local municipal capacity has become a recurring issue as detention populations have grown. States and municipalities increasingly question whether federal agencies adequately assess infrastructure and fiscal impacts before establishing facilities in communities.

What’s Next

Mullin’s confirmation hearing represents an early opportunity for lawmakers to address community concerns about the Roxbury facility. If confirmed as DHS secretary, Mullin indicated he would visit Roxbury to conduct an independent assessment. Future coordination between DHS and Roxbury officials may depend on Mullin’s visit findings and recommendations.

Roxbury officials are expected to continue opposing the facility’s operation without formal consultation. The township may pursue legislative remedies or federal funding to address infrastructure and staffing gaps. Congress may also examine whether DHS acquisition and placement procedures adequately incorporate local input before establishing large-scale facilities.
