California Governor Gavin Newsom declared on Thursday his intent to challenge the Trump administration's decision to withdraw approximately $4 billion in federal funding for the state's long-stalled high-speed rail project. Concurrently, the California High-Speed Rail Authority initiated a lawsuit in the Los Angeles District Court, accusing the Trump administration of power abuse and labeling the funding cancellation as 'arbitrary and capricious.' Since its inception in 2008, the project has consumed substantial funds but progressed at a glacial pace, prompting the Trump administration to halt federal support.
