The Newark, New Jersey, mayor has responded to accusations of trespass at an ICE facility from interim U.S. Attorney Alina Habba.

Acting U.S. Attorney for New Jersey Alina Habba confirmed Baraka’s arrest, saying that the mayor “committed trespass” at the facility.

Baraka has clashed with federal immigration officials ever since the detention facility, privately owned by the GEO Group, opened. Friday’s arrest was a culmination of the back-and-forth, with Newark officials repeating that the owner has not cooperated with local code inspectors.
