California's long-delayed high-speed rail project has become the latest victim in the ongoing battle between President Donald Trump and Gov. Gavin Newsom, as White House officials again aim to cancel billions in federal funding. In response, California officials on July 17 sued to block Trump from halting funding.

California Gov. Gavin Newsom sues the Trump administration for canceling $4 billion in funding for the state's high-speed rail project, calling it political retribution.

California Governor Gavin Newsom on Thursday vowed to fight the "illegal" move by President Donald Trump's administration to rescind $4 billion in federal grant agreements to fund the state's ambitious but long-delayed high-speed rail project.
