Officials at the Department of Homeland Security and the Defense Department are racing to set up multiple tent facilities in Guantanamo Bay, Cuba, to house thousands of migrants, but the scattered efforts have prompted questions internally about who’s in charge and what will happen once people arrive on site.

The Trump administration has flown about 100 immigrants from El Paso to Guantanamo Bay. ProPublica and The Texas Tribune identified nearly a dozen of them and spoke to relatives of three of them.

The US has held migrants at Guantanamo before, with fewer than 100 in recent years. How does Trump’s approach differ?
