DHS Secretary Mullin Rejects "Alligator Alcatraz" Closure Reports

Homeland Security Secretary Markwayne Mullin confirmed the department has no near-term plans to shutter the controversial "Alligator Alcatraz" detention facility.

In a briefing on May 16, 2026, Secretary Mullin addressed escalating reports regarding the potential decommissioning of the soft-sided immigration detention center located in the Florida Everglades. Despite internal documents suggesting rising operational costs and environmental risks, Mullin stated the facility remains a critical component of the administration’s "surge capacity" for immigration enforcement.

The Everglades Stalemate

The facility, nicknamed "Alligator Alcatraz" due to its remote location, has been a flashpoint for both humanitarian and fiscal debate. Recent reports indicated that private contractors had been notified of a June closure, citing costs approaching $1 billion and the extreme difficulty of maintaining safety in a hurricane-prone region.

Secretary Mullin pushed back against these assertions during his recent remarks. "We have not made an announcement that we are shutting it down," Mullin stated, acknowledging that while the site is susceptible to wildfires and tropical storms, the Department of Homeland Security (DHS) maintains robust contingency plans for emergency evacuations rather than permanent closure.

Strategic Enforcement Capacity

Secretary Mullin’s stance aligns with the Trump administration's broader push to maintain high-capacity detention centers near major transit hubs. Since his confirmation in March 2026, Mullin has prioritized funding for the 22 critical agencies within DHS, many of which remain impacted by the ongoing departmental shutdown and budgetary negotiations in Congress.

The Secretary emphasized that the ability to "flex" during migration surges is more important than the current logistical hurdles of the Everglades site. This position comes as the administration also faces scrutiny over new technology proposals, such as biometric "smart glasses" for field agents, which Mullin defends as essential tools for modern border security.

Florida’s Communication Gap

The lack of a definitive timeline has created friction with state officials. Florida Governor Ron DeSantis and the Division of Emergency Management have expressed frustration over what they describe as a "zero communication" policy from the federal government. Florida officials argue they require a clear path forward to manage the local resources supporting the 1,400 detainees currently at the site.

In our review of the recent DHS updates, it is clear the administration is choosing to hold the line on existing infrastructure to avoid any perception of a weakened enforcement posture. While the high operating costs—estimated at nearly $1 billion—continue to draw fire from fiscal hawks, Mullin maintains that national security requirements outweigh the immediate budgetary strain.

Quick Facts: Alligator Alcatraz

• Current Population: Approximately 1,400 detainees.

• Annual Operating Cost: Estimated at $1 billion.

• Environmental Risks: Located within 20 miles of active wildfire zones and high-risk hurricane paths.

• Status: Remains operational per DHS Secretary; no formal closure notice issued to the state.

The refusal to close the facility suggests that DHS is bracing for a significant summer influx of migrants. By keeping "Alligator Alcatraz" online, Secretary Mullin is signaling that the administration will prioritize detention capacity over local environmental or administrative concerns.
