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

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 Trump administration has launched an investigation into California’s high-speed rail project in what could be the first step in clawing back the $4 billion promised by the Biden administration to build out the first section of the line, from Merced to Bakersfield.

Republicans have long targeted high-speed rail, despite its popularity with a majority of Californians. U.S. Rep. Kevin Kiley, who appeared with Duffy and introduced legislation in December to defund it, blasted the railway as “the worst public infrastructure failure in U.S. history.”

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.
