Although Immigration and Customs Enforcement (ICE) has highlighted a rise in illegal immigrant arrests under President Donald Trump, the agency is now grappling with space limitations for detained criminal migrants.

“It’s got these lofty goals, with big numbers, and definitely not a lack of trying and a lack of effort in trying to make that a reality, but is facing practical issues,” Héctor Quirog, a specialist immigration attorney with the Quiroga Law Office in Spokane, Washington, told Fox News Digital.

“Number one, we have got problems with how many detention centers and how many beds are available,” he said. “Because, like it or not, some individuals should have a hearing, and they have to wait somewhere. So we have capacity issues.”

As of Wednesday, only 20 migrants were being held at the base. Sixteen “high-threat illegal aliens” are being held at the detention facility part of the base, also known as Camp 6, and four migrants are being held at a back-up facility due to the inadequacy of the tents.

DHS and ICE have not responded to inquiries regarding what criteria is used to evaluate if a migrant is a high threat.

ICE has said it will require an additional $3 billion due to needing an additional 60,000 detention beds. The additional beds are driven, in part, by the passage of the Laken Riley Act, which requires the DHS to detain illegal immigrants who have been arrested for theft-related crimes. 

“Since the Laken Riley Act requires ERO to immediately detain those noncitizens, ERO would then require, at minimum, 64,000 additional detention beds; however this does not account for other immigration enforcement mandates that may place a need for increased detention capacity,” a letter from ICE said, in response to questions by Rep. Mike Collins, R-Ga.

In Congress, Republicans are preparing to make significant funding changes via the budget reconciliation process. Border security and interior enforcement would likely be top priorities for Republicans, given the issues’ prominence in the 2024 election.
