Newark Mayor Ras Baraka appeared in federal court for a status conference Thursday following his arrest outside an Immigration and Customs Enforcement facility last week. The procedural hearing lasted about 30 minutes and was mostly rooted in the initial discovery.

Newark Mayor Ras Baraka said federal prosecutors him tried to “humiliate and degrade” him by making him give his fingerprints and take a mug shot for a second time after a court appearance on a trespassing charge stemming from his arrest at an immigration detention center.

Ras Baraka, the mayor of Newark, New Jersey, could face a July trial for trespassing after his arrest at a private detention facility that would help the Trump administration’s mass deportation efforts.
