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

Members of Congress were visiting the detention facility as part of congressional oversight. Baraka was with U.S. Reps. Bonnie Watson Coleman, LaMonica McIver and Rob Menendez, all Democrats from New Jersey.

The mayor of Newark was arrested Friday at an ICE detention facility in New Jersey where congressional leaders had scheduled an afternoon “oversight” visit.
