TRENTON - Gov. Chris Christie (R-N.J.) and Sen. Chuck Schumer (D-N.Y.) traded jabs over canceling a tunnel project that would have allowed more commuter trains between New York City and the Garden State.

Schumer called it "terrible, terrible decision" and urged Christie to reconsider.

At a press conference in Newark yesterday to announce the approval of 23 new charter schools across the state, Christie responded to the senator's criticism by saying New Jersey would not be able to afford any cost overruns on the project, adding that unless Schumer was able to contribute another $5 billion, he should "mind his manners on the other side of the Hudson River."

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 the state couldn't afford it.

Schumer said the rail project is essential to help the region grow and thrive.

The state of New Jersey is still fighting with the feds over repaying the $271 million in federal money already spent on the project.
