DERRY, N.H. -- New Jersey taxpayers will continue to be on the hook for the cost of New Jersey State Troopers to follow Gov. Chris Christie out of state on his presidential campaign trail, the governor said Friday.

Christie, speaking outside of a New Hampshire diner where he greeted residents here as part of a five-day tour of the state, said his presidential campaign will not reimburse the state for the added cost associated with his security detail.

"In the end, anywhere I go, the troopers need to go -- whether I want them to go or not," he said. "We're going to continue to conduct this in the same way I've always conducted it."

The governor's office and the State Police weren't saying late last month whether or not the governor's security costs during a presidential campaign would have a cost for New Jersey taxpayers. Christie is expected to spend more time than ever before out of the state in the coming months as he campaigns for the Republican Party's nomination.

The increased travel will mean additional costs associated with providing security for the governor.

In January, it was reported State Police unit tasked with keeping Christie safe has billed the state for nearly $1 million for travel expenses since the governor took office.

The Executive Protection Unit's travel expenses totaled at least $959,856 for Christie's first term in office and the beginning of his second term, records showed. The figure doesn't account for unreleased expenses for the fourth quarter of 2014.

In addition, Christie's recent trips to Great Britain, Canada, and Mexico cost New Jersey taxpayers nearly $124,000, the governor's office announced in June. The figure doesn't include state troopers' overtime or the cost of using State Police vehicles and helicopters to transport the governor.

The State Police submits invoices to the governor's office for any state helicopter travel for political purposes that don't fall under the umbrella of Christie acting in his official capacity as governor.
