Schumer, a Democrat, called it "terrible, terrible decision.'' He's urging Christie, a Republican, to reconsider.
Christie announced in October he would halt the Trans-Hudson Passenger Rail Tunnel, even though construction was already under way. He said the project's costs were skyrocketing and that his cash-strapped state couldn't afford it.
Schumer said the rail project is essential to help the region grow and thrive.
