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

Baraka called for the charge to be dismissed on Thursday: "It is silly, it's petty, it's unlawful — get rid of it!"
