California has withdrawn a lawsuit against the Trump administration that sought to recover roughly $4 billion in federal funds pulled from the state's long-delayed high-speed rail project, after concluding it can no longer rely on the federal government to help deliver the system. The suit was filed after the Federal Railroad Administration began canceling federal grants for the project totaling about $4 billion, arguing the California High-Speed Rail Authority had failed to deliver on commitments amid years of delays and cost overruns.
