U.S. Rep. LaMonica McIver of New Jersey is facing a federal assault charge related to a confrontation at an Immigration, Customs and Enforcement detention facility in Newark earlier this month, officials announced Monday.

McIver, D-10th Dist., was charged with assaulting, impeding and interfering with law enforcement on May 9 at Delaney Hall, interim U.S. Attorney for New Jersey Alina Habba said.

“Today my office has charged Congresswoman McIver with violation of Title 18, United States Code, Section 111(a)(1) for assaulting, impeding and interfering with law enforcement,” Habba, the state’s top federal prosecutor, said in a statement.

“That conduct cannot be overlooked by the chief federal law enforcement official for the State of New Jersey and it is my Constitutional obligation to ensure our federal law enforcement is protected when executing their duties.”

McIver called the charges filed by Habba, an appointee and former lawyer for President Donald Trump, “purely political.”

“Earlier this month, I joined my colleagues to inspect the treatment of ICE detainees at Delaney Hall in my district,” McIver said in a statement. “We were fulfilling our lawful oversight responsibilities, as members of Congress have done many times before, and our visit should have been peaceful and short.

“Instead, ICE agents created an unnecessary and unsafe confrontation when they chose to arrest Mayor Baraka. The charges against me are purely political—they mischaracterize and distort my actions, and are meant to criminalize and deter legislative oversight.”

The news came as Habba also announced that a trespassing charge against Newark Mayor Ras Baraka, a Democrat also running for governor, is being dismissed.

“After extensive consideration, we have agreed to dismiss Mayor Baraka’s misdemeanor charge of trespass for the sake of moving forward,” Habba said.

McIver, along with fellow Democratic New Jersey U.S. Reps. Rob Menendez and Bonnie Watson Coleman, went to Delaney Hall on May 9 for an oversight visit and a scuffle with law enforcement took place as Baraka was arrested at the site.

In a statement released late Monday night, Baraka said he was aware of the charges McIver was facing.

“Congresswoman McIver is a daughter of Newark, past Newark Council President, a former student of mine, and a dear friend,” Baraka said. “I want to be clear: I stand with LaMonica, and I fully expect her to be vindicated.”

Baraka also said he was glad the case against him was dismissed.

“I have had strong relationships with prior U.S. Attorneys, and I plan to speak with the current U.S. Attorney about issues on which we can cooperate,” he said. “As to Delaney Hall, I will continue to advocate for the humane treatment of detainees, and I will continue to press the facility to ensure that it is compliant with City of Newark codes and regulations.

Habba said in her statement Monday night that she invited Baraka to tour Delaney Hall.

“The government has nothing to hide at this facility, and I will personally accompany the mayor so he can see that firsthand,” Habba said.

The U.S. Department of Homeland Security in Trump’s administration alleges that the lawmakers “stormed” Delaney Hall and assaulted officers.

All three Congress members and Baraka have refuted those claims, with Baraka releasing video that showed a guard at the facility allowing him beyond the gate. The Congress members said they also were permitted past the gate prior to Baraka arriving.

The situation escalated, they contend, when Baraka exited the gates after being asked to leave. Four minutes later, guards came out to arrest him, according to body camera video. It was then that the Congress members and an aide encircled the mayor.

Video shows a chaotic scene in which Baraka was restrained, then dragged back through the security gates and handcuffed while McIver and Menendez jostle with the crowd and guards and move beyond the gates with the mayor.

“They made this a violent scene that we were unfortunately all a part of,” Menendez said during an interview on CNN last weekend. “And it’s something that should really shock all Americans.”

Earlier that day, the mayor came to Delaney Hall, as he had two other days that week and again last week, to serve ICE with violation notices from the city of Newark. The notices allege the Geo Group, which is contracted by ICE to operate the 1,000-bed facility, was refusing city officials entry to the facility and improperly padlocking the front gate.

He returned in the afternoon when the Congress members were already beyond the gate, waiting to be let in to the center for an oversight tour. None of the videos released by the federal government or city officials shows the moment the Congress members arrived or were admitted in.

In the videos, ICE security guards can be seen telling Baraka that the Congress members “are different” and can be allowed in, but he’s told to leave, which he does to a round of applause from protestors.

Minutes later, the agents return in an attempt to arrest Baraka. During the scuffle, McIver and some of the guards can be seen pushing each other. Once beyond the gates, McIver accuses one of the guards of assaulting her and another officer attempts to break up the verbal dispute.

Since then, the Department of Homeland Security and the elected officials from New Jersey have sparred over the portrayal of the events.

The department said two members of Congress “stormed the gate and broke into the detention facility” and called it “a bizarre political stunt.”

McIver denied the department’s accusation that she body-slammed an agent.

“I honestly do not know how to bodyslam anyone,” McIver said. “There’s no video that supports me bodyslamming anyone.”“

U.S. Homeland Security Secretary Kristi Noem, a member of Trump‘s cabinet, said she wants the three Democratic members of Congress to be formally admonished by the House of Representatives and relieved of their committee assignments.

Rep. Earl L. “Buddy” Carter, R-Ga., has introduced a resolution to strip them of their committee assignments.

Late Monday night, joint Democratic House leadership, including House Democratic Leader Hakeem Jeffries, said the criminal charge against McIver is “extreme, morally bankrupt and lacks any basis in law or fact.”

Menendez, D-8th Dist., called the charges “unprecedented and politicized.”
