Rep. LaMonica McIver (D-NJ) pleaded not guilty to the federal assault charges levied against the congresswoman over her visit to an Immigration and Customs Enforcement facility in Newark, New Jersey, where she allegedly obstructed federal officers from arresting the city’s mayor.

McIver denied the charges at her arraignment in Newark on Wednesday. McIver faces a three-count indictment for “assaulting, resisting, and impeding” Department of Homeland Security officials in the viral altercation outside the immigration facility last month.
