TRENTON, N.J. (AP) — U.S. Rep. LaMonica McIver was indicted Tuesday on federal charges alleging she assaulted and interfered with immigration officers outside a New Jersey detention center while Newark’s mayor was being arrested after he tried to join a congressional oversight visit at the facility.

Acting U.S. Attorney for New Jersey Alina Habba announced the grand jury indictment in a post on X.

“While people are free to express their views for or against particular policies, they must not do so in a manner that endangers law enforcement and the communities those officers serve,” Habba said.

In a statement, McIver said the charges amounted to the Trump administration trying to scare her.

“The facts of this case will prove I was simply doing my job and will expose these proceedings for what they are: a brazen attempt at political intimidation,” she said.

McIver, a Democrat, was charged in a complaint by Habba last month with two assault charges stemming from the May 9 visit to Newark’s Delaney Hall — a 1,000-bed, privately owned facility that Immigration and Customs Enforcement uses as a detention center.

The indictment includes three counts of assaulting, resisting, impeding and interfering with federal officials. Habba said two of the counts carry a maximum sentence of up to eight years in prison. A third has a maximum sentence of one year.

McIver’s lawyer, former U.S. Attorney for New Jersey Paul Fishman, said in a statement that they would challenge the allegations “head-on” in court.

“The legal process will expose this prosecution for what it truly is — political retaliation against a dedicated public servant who refuses to shy away from her oversight responsibilities,” Fishman said.

The indictment is the latest development in a legal-political drama that has seen President Donald Trump’s administration take Democratic officials from New Jersey’s largest city to court, tapping into the president’s immigration crackdown and Democrats’ efforts to respond. The prosecution of McIver is a rare federal criminal case against a sitting member of Congress for allegations other than fraud or corruption.

At the same visit that resulted in McIver’s charges, Newark Mayor Ras Baraka was arrested on a trespassing charge, which was later dropped. Baraka is suing Habba over what he said was a malicious prosecution.

A nearly two-minute clip released by the Homeland Security Department shows McIver on the facility side of a chain-link fence just before the arrest of the mayor on the street side of the fence, where other people had been protesting. She and uniformed officials go through the gate, and she joins others shouting that they should circle the mayor. The video shows McIver in a tightly packed group of people and officers. At one point, her left elbow and then her right elbow push into an officer wearing a dark face covering and an olive green uniform emblazoned with the word “Police” on it.

It isn’t clear from police bodycam video whether that contact was intentional, incidental or a result of jostling in the chaotic scene.

The complaint says she “slammed” her forearm into an agent then tried to restrain the agent by grabbing him.

The indictment says she placed her arms around the mayor to block his arrest and repeats the charges that she slammed her forearm into an agent and grabbed the agent.

New Jersey Reps. Bonnie Watson Coleman and Rob Menendez had joined McIver at the detention center that day. They and other Democrats have criticized the arrest and disputed the charges as well.

By law, members of Congress are authorized to go into federal immigration facilities as part of their oversight powers, even without notice. Congress passed a 2019 appropriations bill that spelled out the authority.

McIver, 38, first came to Congress in September in a special election after the death of Rep. Donald Payne Jr. left a vacancy in the 10th District.

She was then elected to a full term in November. A Newark native, she served as the president of the Newark City Council from 2022 to 2024 and worked in the city’s public schools before that.
