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.

Transportation Secretary Sean Duffy has asked for a compliance review of California's controversial High Speed Rail project.

Transportation Secretary Sean Duffy put California's high speed rail project on notice Thursday, saying it is years overdue and billions over budget.

California voters in 2008 approved nearly $10 billion in bond money to build a high-speed rail line connecting Los Angeles and San Francisco that was supposed to be running by 2020.

Duffy, speaking at Union Station in Los Angeles on Thursday morning, said the Federal Railroad Administration will review the rail project and its leadership.

Transportation Secretary Sean Duffy said the government would conduct a “compliance review” on a $3.1 billion grant, potentially threatening the viability of the troubled, controversial high-speed rail project.

The Trump admin is putting a "disastrous" high-speed rail project in California on notice after it started almost two decades ago and has "no rail" being built.

The transportation secretary, Sean Duffy, said the government would conduct a “compliance review” on a $3.1 billion grant, potentially threatening the viability of the troubled project.

While U.S. Transportation Secretary Sean Duffy questioned the cross-state high-speed rail project, he praised the Las Vegas-to-Los Angeles effort.

The California High-Speed Rail Authority (CHSRA) has received several funding grants for the project from the federal government under the Biden administration in recent years, including a $US 3.1bn Federal-State Partnership for Intercity Passenger Rail Grant, the single largest federal allocation for the project, in December 2023.
