The Trump administration could pull $4 billion in federal funding from California's high-speed rail project within 37 days, following a Department of Transportation compliance review.

The Trump administration said it would pull roughly $4 billion in federal funding for California’s long-planned high-speed train, a project that has, over decades, become an avatar for the country’s declining ability to complete transformative new infrastructure.

The threat to cancel $4 billion in grants echoes Trump’s earlier move to withdraw $1 billion from the project during his first term, when he dismissed it as “a green disaster.”
