A federal prosecutor on Monday charged Rep. LaMonica McIver (D-NJ) with assaulting federal law enforcement during a protest at an Immigration and Customs Enforcement detention facility earlier this month. The prosecutor simultaneously dropped a trespassing charge against Newark Mayor Ras Baraka stemming from the same incident.

In a statement, U.S. Attorney Alina Habba for the District of New Jersey said her office decided not to prosecute Baraka “for the sake of moving forward,” but would move ahead with charges against McIver under Title 18, U.S. Code Section 111, which criminalizes assaulting or impeding federal officers. Habba said she attempted to resolve the matter with McIver without charges, but the congresswoman declined.
