A federal judge has temporarily blocked the Trump administration from spending $1.8 billion allocated for what the president has called a "weaponization" fund, as reported by Reuters. The ruling, issued on May 29, 2026, halts the disbursement of funds pending further legal review.

The injunction comes amid growing scrutiny of the administration's use of federal resources for immigration enforcement and border security initiatives. The $1.8 billion fund, established earlier this year, was intended to support expanded detention operations, deportation efforts, and what the administration described as countering the "weaponization" of immigration policy by previous governments. Critics have argued the fund lacks proper congressional oversight and diverts resources from other federal programs.

The temporary restraining order does not specify the duration of the block, but requires the administration to submit detailed accounting of how the funds were intended to be allocated. The judge's order applies to all expenditures from the designated account, including contracts already in negotiation with private detention facility operators and technology vendors for border surveillance systems. The ruling does not affect other immigration enforcement budgets already approved through standard appropriations processes.

Legal challenges to the fund have centered on separation of powers concerns, with plaintiffs arguing that the executive branch circumvented Congress by reprogramming funds without proper authorization. The case is being closely watched by immigration advocacy organizations and state attorneys general who have filed amicus briefs supporting the injunction.
