Roughly 300 migrants have been detained at the U.S. naval base since President Donald Trump took office. Most of those housed at the base had serious criminal histories, gang affiliations, or were ordered to be deported by federal judges.
A Department of Defense official told the Washington Post on Wednesday that all remaining migrants held at the facility had been flown back to the U.S. for unknown reasons.

Most of the migrants being held at the base had already been deported to Venezuela. The remaining 40 migrants were sent to an ICE facility in Louisiana.
The Washington Examiner reached out to the Department of Homeland Security for further comment and to inquire about whether more migrants would be sent to Guantanamo Bay.
Guantanamo Bay can hold up to 2,500 people in its migrant detention site. The migrant facilities are separate from the more well-known terrorist detention facilities.

The migrants taken to the base were flown in on military aircraft, a process that drew criticism due to its high cost. Those not deported were flown back to the U.S. on ICE air, a much less expensive option.
Guantanamo Bay had been previously cleared out in late February when 177 of the 178 migrant detainees were flown to Venezuela after negotiations with Caracas.
