Latest estimates pin the cost at $77 billion and completion in 2033.
"In a tweet on Wednesday, Trump called the project a "'green disaster'".
Newsom responded, saying: "Fake news".
Given the challenges, Newsom has now proposed prioritizing a segment of the high-speed rail link specifically in Central Valley. "This is California's money, allocated by Congress for this project".
"As we've said previously, we support strong and effective privacy legislation in the USA that gives people the right to control their information and holds companies to high standards in explaining what data they have and how they use it", a spokesman said in an email. Reporters at the Los Angeles Times have done an excellent job tracking down and reporting on the many, many screw-ups along the way that got the train to this point and essentially forced Newsom's hand.
California was one of the first USA states to champion a government-owned high-speed rail system like those that are ubiquitous in parts of Europe and Asia.
When it was launched, the total cost for the train, which was slated to run from San Francisco to Los Angeles and ease serious gridlock in the region, was estimated at $40 billion.
"The money was granted to California as part of President Barack Obama's stimulus, which set aside "$8 billion in federal stimulus money to create 13 high-speed rail corridors", the New York Times reported at the time.
"Merced, Fresno, Bakersfield, and communities in between are more dynamic than many realize".
He said the state would not "walk away from this whole endeavour", because "abandoning high-speed rail entirely means we will have wasted billions of dollars with nothing but broken promises and lawsuits to show for it.' He was also 'not interested" in returning the$3.5bn of federal funding. The original plan was to connect Los Angeles to San Francisco.
So now President Trump wants federal taxpayers' money back.
Newsom, 51, has sparred repeatedly with Trump and excerpts of his speech indicate he'll rebut pieces of the State of the Union address delivered by Trump. Newsom said the project has been botched and suffered "too many years of neglect" from bureaucrats and decision-makers.
"We need to see a champion emerge", Saltzman said.
"While platforms are fast and loose with consumer data, they are not so willing to share what they are doing with the data or how much they are profiting", said James Steyer, founder of Common Sense Media, which played a central role in drafting and passing the California Consumer Privacy Act in 2018.
