California House Republicans are pushing the Trump administration to block a $650 million federal grant to fund electrification of a San Francisco Bay Area train system that would also benefit the state's high-speed rail project.

The San Francisco Chronicle reports that the members of the state's GOP delegation sent a letter asking the Transportation Department to stop approval of a grant needed to electrify a Caltrain line between San Jose and San Francisco.

Future high-speed bullet trains would need electrified rails.

The letter sent to Transportation Secretary Elaine Chao asks for a delay until an audit of the bullet train's finances is completed.

It also adds that providing additional funding at this time to the authority would be an irresponsible use of taxpayer dollars.
