When a New Jersey governor leaves office, they are given six months of State Police security detail.

But former Gov. Chris Christie's will end a few weeks early.

Gov. Phil Murphy's predecessor is set to have his security detail stripped Saturday, two sources with knowledge of the State Police's plans told NJ Advance Media on the condition of anonymity because they weren't authorized to talk openly about the State Police's Executive Protection Unit.

The decision to end Christie's after-office protection comes from Murphy's administration, not the State Police, the sources said.

Christie's detail will end about two weeks ahead of the six-month mark the security would officially conclude. He left office on Jan. 16.

Former governors get a trimmed-down version of the security detail they have while in office. It usually consists of a single State Police EPU officer.

A spokesman for Murphy, Dan Bryan, deferred comment to State Police, which declined to comment on executive protective details.

Christie also declined to comment. However, the former governor confirmed he didn't request for his detail to end early.

Murphy was asked at a public event Tuesday whether he was the person who gave the order to end Christie's detail ahead of schedule, Murphy wouldn't say.

"That's not something we talk about," he said at an unrelated news conference at the Rutherford train station. "I think you need to direct that to the State Police."

Word was sent to the former governor about the conclusion of the detail on Monday.

The Murphy administration's decision to pull the security early comes at the same time Murphy has repeatedly invoked Christie's name during budget negotiations with the state's Democratic-controlled Legislature.

Murphy, a Democrat, has accused lawmakers of "keeping the legacy of Chris Christie alive and well in Trenton" when they sent him a budget that he criticized for relying on "gimmicks" and "ticking time bombs."

"This is not Chris Christie's New Jersey," Murphy said last week.

Lawmakers, meanwhile, have also referred to the former Republican governor when talking about Murphy.

State Senate President Stephen Sweeney, for example, has accused Murphy of using Christie tactics to put pressure on lawmakers to support his budget proposal, which Sweeney is at odds with.

According to Sweeney, Murphy has "threatened" legislators -- whether saying a lawmakers' appointments could be at risk or their pet projects could be in jeopardy -- to break with Sweeney and get behind the Murphy budget.

"That ain't Mr. Nice Guy," Sweeney, D-Gloucester, said last week. "He resembled Christie more than Christie."

Murphy was asked about Sweeney's claim on Monday.

"I said to folks, 'Do you realize the consequences of what will happen?' People have to understand that there are real consequences," Murphy said, referring to the lack of funding for certain projects or causes if lawmakers send him a budget that doesn't have a funding source.
