The president wants to send 30,000 immigrants in the country illegally to the Cuban naval base infamous for its role during the War on Terror. How will he do it?

Human rights groups have accused U.S. authorities of using Guantánamo Bay for decades to detain migrants fleeing Haiti, Cuba and other Caribbean nations.

As tents went up in Guantanamo Bay, Cuba to hold migrants, attorneys at the Department of Homeland Security and Pentagon were still trying to determine whether it was legal to take the unprecedented step of flying migrants from the US southern border to the facility,

President Donald Trump, who made the deportation of immigrants a central part of his campaign and presidency, said the U.S. will use a detention center at Guantánamo Bay, Cuba, to hold tens of thousands of the "worst criminal aliens.

The US has maintained a migrant detention facility there for decades that is separate from the notorious high-security jail for foreign terror suspects, including alleged 9/11 mastermind Khalid Sheikh Mohammed.

In a lawsuit, the groups asked a judge to enable lawyers to communicate with the men in case they would like legal representation.

A coalition of civil liberties and immigrant rights groups are suing to get access to immigrants transferred from the U.S. to detention at Guantánamo Bay in Cuba under President Trump 's recent order.
