A new attorney is stepping in to replace Peter Florrick on "The Good Wife."

John Leguizamo ("ER") is guest-starring as the new Cook County State's Attorney, according to TVLine. Leguizamo's character, who took over Peter's (Chris Noth) position after he was elected governor, is described as a "well-like leader" who strives to make the State Attorney's Office fair for everyone.

The actor will reportedly appear in one episode, which will air when the show returns from hiatus.

Michael J. Fox will also reprise his role on the hit CBS series for multiple episodes. According to TVLine, the actor has closed a deal with CBS to reprise his role as Alicia's legal rival, Louis Canning, for multiple episodes at the end of this season.

Rumors of Fox's potential return surfaced last month at the Television Critics Association winter press tour. At the tour, series co-creator Robert King said, "We're trying to make that work. Because he finished filming [The Michael J. Fox Show], so it looks like we're going to get a chance to get him back."

When the series returns in March, the potential election scandal will continue to make waves. Series co-creator Michelle King said the scandal "continues to play over the rest of the season. I don't know if it will be a part of the season finale, but it's definitely not over."

When the show resumes, it's clear that Alicia will find out who tampered with the ballot box during Peter's election.

Before the series went on hiatus, an incriminating video surfaced that suggested that Peter (Chris Noth) rigged the election to ensure his victory. Michelle King told TVGuide that his alleged crime will stir up old feelings of betrayal for Alicia (Julianna Margulies).

"We wanted to be true to the idea of the relationship and what started at the beginning of the series, which was this incredible betrayal," King said. "Then, yes, they came together, but even when there's a whiff of something for her to lose her trust, she reacts a lot because of that initial betrayal."

To make matters worse, Alicia's son Zach (Graham Phillips) is involved in the growing scandal, because he discovered the unsealed box of ballots.

"There's a problem there," Robert King told TVGuide. "[Alicia's] cynical enough or pragmatic enough to not mind that there's some dirty work to be done with the job. What she's really against is when the dirty work throws back on their kids. And that's one area that she will draw the line [on] no matter what."

Now, it will be up to Eli (Alan Cumming) to get Peter back on the right path.

Robert King said that Peter's newest political scandal will mirror a real-life scandal that is currently making headlines.

"It's all about Chris Christie," he said. "It's so much about people in charge trying to deflect things on their underlings," Robert King says. "When investigators follow things, do they follow the smoking gun or where the money goes? Does it always go up higher and higher? Peter's in a lot of trouble, actually."

The producers also said that Alicia and Will's (Josh Charles) heated storyline will die down a bit, and the two will have to learn to live with their complicated relationship. While Will won't go head-to-head with Alicia in court for awhile, he will go up against a new court room foe. Matthew Goode is joining the series as a prosecutor who is the legal counsel for Jeffrey Grant.

"He's a witty intellectual who is very much Will's peer. They compete against each other in the court with the Hunter Parrish case," Robert King said.

"Weeds" alum Hunter Parrish guest-starred earlier on in the season as Jeffrey Grant, a college student who is arrested on a fake DUI then accused of murdering a female classmate. After his DNA was found to be a 100 percent match for the killer, the case was sent to retrial, and he is now waiting in jail.

"The Good Wife" returns on Sunday, March 9 at 8 p.m. EST on CBS.
