TRENTON - Gov. Chris Christie says the Amtrak train derailment is "really disconcerting" and hopes authorities will get to the bottom of what caused it.
Christie told reporters in New Hampshire on Wednesday that he's been riding the route between New York and Washington for more than a decade.
He says his thoughts go out to the families of those who have been lost and injured.
The Republican governor also says he instructed the state's emergency management personnel to reach out to authorities in Philadelphia to offer their assistance, but they said they didn't need it.
Christie says he's "fascinated" to know what caused the derailment and hopes authorities will do what's needed to try to prevent future incidents.
Christie is in the early-voting state as he considers a presidential run.
