American Civil Liberties Union of New Jersey Executive Director Amol Sinha, in a statement sent to Newsweek via email on Friday: "The arrest of Mayor Ras Baraka by the Department of Homeland Security is a shameful escalation of the Trump administration's intimidation campaign against officials who refuse to do their bidding."

Newark Mayor Ras Baraka was arrested Friday at an ICE Detention Center where he was protesting its opening, a federal prosecutor said.

Ras Baraka, who was released from custody Friday night, is one of six major Democratic candidates competing in the gubernatorial primary on June 10.
