During the early days of President Donald Trump's tenure, Guantánamo Bay became a focal point for detaining criminal illegal aliens, as Trump authorized the Pentagon to prepare 30,000 beds at the facility. The administration faced logistical challenges in increasing the capacity of the naval base, with efforts to erect tents being stalled due to unmet standards. Despite these issues, Defense Secretary Pete Hegseth emphasized Gitmo's critical role in immigration enforcement, describing it as the front line against threats from the southern border. The U.S. also collaborated with El Salvador to transfer several hundred gang members to a specialized detention center there. Ultimately, the initial group of migrants at Guantánamo was returned to the United States, and the future use of the facility for migrant detention remains uncertain.

President Trump's early decision to use Guantánamo Bay for detaining criminal illegal aliens was part of a broader strategy to combat immigration-related crime, with emphasis on those deemed 'worst of the worst'.

The plan involved preparing accommodations at the naval base for up to 30,000 individuals, although efforts faced setbacks due to the tents not meeting necessary detention standards.

Defense Secretary Pete Hegseth highlighted the significance of Guantánamo in supporting immigration enforcement, framing it as a key element in protecting the southern U.S. border.

Complications arose in the execution of the plan, as the military lacked clear guidelines for the setup of migrant detention facilities, leading to a halt in further construction.

Concurrent to the Guantánamo initiative, the U.S. partnered with El Salvador to address gang-related threats, sending hundreds of gang members to the country's 'Terrorist Confinement Center'.

The logistical challenges culminated in the reallocation of the remaining detainees back to U.S. facilities in Louisiana, after difficulties in expanding Guantánamo's capacity.

The future of using Guantánamo Bay for detaining migrants remains in question, as the U.S. government continues to explore alternative solutions for handling high-threat illegal aliens.
