The Trump administration has awarded a $1.26 billion contract to build and operate what would become the country’s largest immigrant detention center at Fort Bliss, an Army base in El Paso, Texas. The work would turn the base, with more than 1 million acres of space and an airport, into a sprawling tent camp with 5,000 beds.

The latest detention facility will house up to 5,000 detainees and function as a central hub for deportation operations.
