The Trump administration is once again seeking to end federal funding for California's high-speed rail project, following a lengthy review of the state's progress that found "no viable path" to completion.

The Trump administration intends to pull some $4 billion in federal funding from California's long-delayed high-speed rail project, transportation officials say. Duffy said California's rail agency has 37 days to respond to the findings of the review before the two grants worth some $4 billion would be terminated.

A federal probe by the Trump Administration determined the California High Speed Rail Authority in default on terms of two federal grant awards.
