The Trump administration is once again targeting California's controversial high-speed rail project, with federal transportation officials on Thursday announcing an investigation and possible withdrawal of about $4 billion in federal funding.
Voters first approved $10 billion in bond money in 2008 for a project designed to shuttle riders between San Francisco and Los Angeles in less than three hours. It was slated to cost $33 billion and be finished by 2020. But the project has been beset by funding challenges, cost overruns and delays.
