A US federal judge has maintained a block on the Trump administration’s plan to divert $1.8 billion towards the construction of a wall along the US-Mexico border. The funds were originally allocated by Congress for other purposes, prompting legal challenges arguing the move exceeded presidential authority. The judge’s indefinite continuation of the injunction prevents the administration from reallocating the money while the legal battle continues. The lawsuit, brought by several states, contends the funding diversion violates the separation of powers and congressional appropriation authority. This decision represents another setback for the former president’s signature border wall project. The blocked funds were intended to cover costs associated with building sections of the wall in California, New Mexico, and Texas. The legal proceedings are expected to continue, with the ultimate outcome potentially hinging on future court rulings.
