Transportation Secretary Sean Duffy was savagely booed Thursday during a news conference on California’s high-speed rail project at the Union Station in Los Angeles. The Donald Trump appointee blasted state authorities for mismanaging the once “exciting” project and claimed it had amounted to a waste of funds.

The Trump administration has launched a formal review of the California high-speed rail project, questioning the state's ability to complete the project and the allocation of federal funds.

Secretary of Transportation Sean Duffy said the California high-speed rail project will continue to cost taxpayers billions of dollars with no definitive timeline for completion.
