Department of Homeland Security sources confirmed that 13 Venezuelans are being flown to Guantánamo Bay Detention Camp in Cuba, some of whom are members of the violent Tren de Aragua criminal organization.

It's not clear how many beds Guantanamo has, or how Mr. Trump arrived at that number. The president has previously floated the idea of sending migrants with criminal backgrounds to be detained or imprisoned outside the U.S., although the logistics and legalities of such a feat remain unclear.
