Trump admin makes aggressive move to expand illegal immigrant detention: 'Outside the box'

In a statement, the Federal Bureau of Prisons said it is helping Immigration and Customs Enforcement (ICE) "by housing detainees and will continue to support our law enforcement partners to fulfill the administration's policy objectives."

The bureau said that for privacy, safety and security reasons, it does not comment on the legal status of any individual, "nor do we specify the legal status of individuals assigned to any particular facility, including numbers and locations."

The Associated Press reported that facilities in Los Angeles, Miami and Atlanta are being used for detention.

ICE currently has just under 42,000 beds available to it, and it has been exceeding capacity under the current administration. The administration has been pushing hard to get more beds and detention space, but sources tell Fox that it typically takes around 30 days for contractors to deliver, given the time it takes to identify buildings, hire people, conduct background checks and comply with related requirements. That help is expected soon.

Fox also reported that ICE is working with the BOP to identify space to house illegal immigrants, as well as Customs and Border Protection (CBP), where there may be unused space in soft-sided facilities. Fox News Digital was also told that, as of this week, officials are being instructed that any release of an illegal immigrant in ICE custody must be personally signed off on by acting ICE director Caleb Vitello. 

Meanwhile, the administration is using Guantánamo Bay to house up to 30,000 detainees, with the second flight of migrants leaving for the facility on Thursday.

 "We are looking well outside the box," a senior ICE official told Fox News Digital.

"The Biden administration cut down so many of our beds, and they canceled so many contracts. And the problem with that is you can't just immediately turn those back on. It's not a switch, it's a dial," they said.
