The New Jersey traffic scandal that has rocked the world of politics is filled with both familiar names and below-the-radar operatives and appointees who were largely unknown to people beyond the world of those who work in or cover Garden State politics on a daily basis.

So who is involved? Who says they are not? And who has been caught in the middle?

Below we give you the five biggest names you need to know.

1. Chris Christie

Who is he? The Republican governor of New Jersey and a likely candidate for president in 2016. Christie won a second term last November in a landslide and is viewed as one of the GOP's brightest stars.

Where does he fit in? A handful of Christie aides and appointees were apparently involved in a politically motivated decision to close access lanes from Fort Lee to the George Washington Bridge last year. Christie has repeated that he played no part in the decision to target Fort Lee and only learned of it through a news report on Wednesday. He fired one of the aides at the center of the scandal and cut another loose.

What's next? It depends on what else we learn about this story. If this is an isolated incident, it's likely something that Christie can survive. But if similar examples surface, Christie's no-nonsense image is going to take a major hit -- even if he is not directly involved. 

2. Bill Stepien

Who is he? Christie's former campaign manager and one of his closest political advisers. Stepien was expected to play a leading role in a potential 2016 presidential campaign. But that's not likely to be the case anymore. Stepien has been encouraged not to run for state party chair and Christie has pretty much banished him from his circle of advisers.

Where does he fit in? While it's not clear that Stepien knew about the decision to close the lanes, he was in touch with a Christie appointee about fallout in the media as a result of the action, as revealed by e-mails disclosed this week.

What's next? It's hard to see how Christie welcomes Stepien back into the fold any time soon.

Who is she? Christie's now former deputy chief of staff. She was fired by the governor.

Where does she fit in? An e-mail from Kelly to a Christie appointee at the Port Authority of New York and New Jersey is what people will probably remember most about all of this. "Time for some traffic problems in Fort Lee," she wrote, clearly illustrating that she wanted to target the city.

What's next? It's safe to say Kelly and the Christie world have parted ways for good. But the question is what, if anything, she will say moving forward about this incident. So far, mum's been the word.

Who is he? Christie appointed him to the Port Authority. The two also went to high school together -- though Christie sought to downplay the nature of their relationship in his Thursday news conference.

Where does he fit in? Wildstein responded to Kelly's e-mail about traffic problems with, "Got it." He resigned late last year as word of scandal started brewing publicly.

What's next? Like most of the people on this list, it's an open question dependent on what new information comes out about the scandal. Wildstein is being tight-lipped right now, though: He pleaded the Fifth at a hearing before state legislators Thursday.

Who is he: The Democratic mayor of Fort Lee.

Where does he fit in: Sokolich did not endorse Christie in the 2013 election. While there is no evidence in the communications released so far that this is the reason that the lanes in his town were closed, that's the explanation many critics of Christie and his allies have been pushing.

What's next? Christie met with Sokolich Thursday to do some damage control. After the meeting, the mayor said he took Christie at his word that he had nothing to do with it. His name will continue to be in the news because it was his town where the whole thing unfolded.

Who is she: The Democratic Senate majority leader in the New Jersey state assembly and one of Christie's most vocal opponents.

Where does she fit in: Weinberg represents Fort Lee, the city gridlocked by the traffic jams, and there has been some speculation that she was the real target of Christie's aides. In a press conference 12 hours before the emails arranging the jams were sent, Christie had called Weinberg and other Senate Democrats "animals" for the way they were treating his nominations for the state Supreme Court. At the same press conference, Christie yanked a Republican justice off the court to spare her a contentious reappointment hearing. The justice was also the wife of a close Christie aide. Weinberg has been aggressively probing the lane closures for months, including showing up at Port Authority board meetings to question commissioners. Christie and Weinberg have a long history: he once urged reporters to “take a bat” to Weinberg, and  afterwards, she displayed two mini Louisville Sluggers on her office mantle – one with her name engraved on it and a noticeably smaller one with Chris Christie’s name.

What's next? No link to Weinberg has been proven, but expect to see plenty of questions raised in the coming days about Christie's relationship with her and about his bipartisan bona fides.
