NEWARK, N.J. — Newark Mayor Ras Baraka sued New Jersey’s top federal prosecutor on Tuesday over his arrest on a trespassing charge at a federal immigration detention facility, saying the Trump-appointed attorney had pursued the case out of political spite.

Baraka, who leads New Jersey’s biggest city, is a candidate in a crowded primary field for the Democratic nomination for governor next Tuesday. The lawsuit against interim U.S. Attorney for New Jersey Alina Habba coincided with the day early in-person voting began.

The lawsuit seeks damages for “false arrest and malicious prosecution,” and also accuses Habba of defamation for comments she made about his case, which was later dropped.

Citing a post on X in which Habba said Baraka “committed trespass,” the lawsuit says Habba issued a “defamatory statement” and authorized his “false arrest” despite “clear evidence that Mayor Baraka had not committed the petty offense of ‘defiant trespass.’” The suit also names Ricky Patel, the Homeland Security Investigations agent in charge in Newark. Baraka’s attorney, Nancy Erika Smith, said they also expect to sue President Trump’s administration but are required to wait six months.

“This is not about revenge,” Baraka said during a news conference. “Ultimately, I think this is about them taking accountability for what has happened to me.”

Emails seeking comment were left Tuesday with Habba’s office and the Homeland Security Department, where Patel works.

Videos capture chaos outside the detention center

The episode outside the Delaney Hall federal immigration detention center has had dramatic fallout. It began on May 9 when Baraka tried to join three Democratic members of Congress — Rob Menendez, LaMonica McIver and Bonnie Watson Coleman — who went to the facility for an oversight tour, something authorized under federal law. Baraka, an outspoken critic of Trump’s immigration crackdown and the detention center, was denied entry.

Video from the event showed him walking from the facility side of the fence to the street side, where other people had been protesting. Uniformed officials then came to arrest him. As they did, people could be heard urging the group to protect the mayor. The video shows a crowd forming and pushing as officials led off a handcuffed Baraka.

He was initially charged with trespass, but Habba dropped that charge last month and charged McIver with two counts of assaulting officers stemming from her role in the skirmish at the facility’s gate.

U.S. Magistrate Judge Andre Espinosa rebuked Habba’s office after moving to dismiss the charges. “The hasty arrest of Newark Mayor Ras Baraka, followed swiftly by the dismissal of these trespassing charges a mere 13 days later, suggests a worrisome misstep by your Office,” he wrote.

McIver decried the charges and signaled she plans to fight them. A preliminary hearing is scheduled later this month.

Baraka said the aftermath of the withdrawn charge meant he had to explain it in the media and argue his case when he had done nothing wrong.

“I want somebody to apologize, write a letter, say this was wrong, come out and say, ‘We shouldn’t have done this,’” he said.

New Jersey targeted over its so-called sanctuary policies

Delaney Hall, a 1,000-bed facility, opened earlier this year as a federal immigration detention facility. Florida-based Geo Group Inc., which owns and operates the property, was awarded a 15-year contract valued at $1 billion in February. The announcement was part of the president’s plans to sharply increase detention beds nationwide from a budget of about 41,000 beds this year.

Baraka sued Geo soon after that deal was announced.

Then, on May 23, the Trump Justice Department filed a suit against Newark and three other New Jersey cities over their so-called sanctuary policies. There is no legal definition for sanctuary city policies, but they generally limit cooperation by local law enforcement with federal immigration officers.

New Jersey’s attorney general has a statewide directive in place prohibiting local police from collaborating in federal civil immigration matters. The policies are aimed at barring cooperation on civil enforcement matters, not at blocking cooperation on criminal matters. They specifically carve out exceptions for when Immigration and Customs Enforcement supplies police with a judicial criminal warrant. The Justice Department said, though, the cities won’t notify ICE when they’ve made criminal arrests, according to the suit.

It’s unclear whether Baraka’s role in these fights with the White House is affecting his campaign for governor. He’s one of six candidates seeking the Democratic nomination in the June 10 election to succeed term-limited Democratic Gov. Phil Murphy.

On Tuesday, Baraka explained the timing of the suit as an effort to get the case before the court before it was too late. He described the arrest and fallout as a distraction during the campaign.

“But I also think that us not responding is consent,” he said.

In a video ad in the election’s final weeks, Baraka has embraced a theme his rivals are also pushing: affordability. He says he’ll cut taxes. While some of the images show him standing in front of what appears to be Delaney Hall, he doesn’t mention immigration or the arrest specifically, saying: “I’ll keep Trump out of your homes and out of your lives.”

Trump has endorsed Jack Ciattarelli, one of several Republicans running in the gubernatorial primary. Ciattarelli has said if he’s elected, his first executive order would be to end any sanctuary policies for immigrants in the country illegally.
