Trump Administration Moves More Migrants to Guantánamo Bay

The military transported about 15 immigration detainees from Texas to the U.S. base at Guantánamo Bay, Cuba, on Sunday, bringing in new migrants who have been designated for deportation days after it cleared the base of its first group of deportees.

No new migrants had been sent to the base since the Homeland Security Department cleared it of 178 Venezuelans on Thursday.

A brief announcement did not identify the nationalities of the newest arrivals. Nor did it give exact figures. But a government official said they were in the category of “high-threat illegal aliens,” and therefore were being held in Camp 6, a prison that until last month housed detainees in the war on terrorism.

Last week, the Trump administration delivered 177 Venezuelan men who had been designated for deportation from Guantánamo to the Venezuelan government on an airstrip in Honduras.

It is unclear why those men had to be taken to Guantánamo on 13 military flights from El Paso from Feb. 4 to Feb. 17, and then shuttled to an air base in Honduras on two chartered U.S. aircraft. On Feb. 10, Venezuela sent one of its commercial airliners to El Paso for 190 other Venezuelan citizens the United States wanted to deport.

Juan E. Agudelo, an Immigration and Customs Enforcement official who is based in Miami, said in a court filing on Thursday that the administration was using Guantánamo to “temporarily house aliens before they are removed to their home country or a safe third country.” Mr. Agudelo was unable to predict the length of the average stay for a migrant before deportation beyond “the time necessary to effect the removal orders.”

Sunday’s transfer happened without advanced notice. The U.S. government declined a request last week from a consortium of U.S. civil liberties lawyers that asked for 72 hours’ notice before more people in homeland security custody were sent there.

The government said in a filing that it had made arrangements for would-be deportees being held there to speak by phone with lawyers. Three of the men who were sent home on Thursday had one-hour calls with lawyers who had sued for access to the migrants and specifically named those three.
