Newark Mayor Ras Baraka spoke after his arrest and said his city would continue to fight companies operating immigration detention centers in New Jersey in court.

"I know others are planning protests that others are planning, if I feel obliged to be there," Baraka told Rev. Al Sharpton on MSNBC on Saturday afternoon. "This does not stop the city from arguing with the geographic group and we will continue to be in court with them."

Baraka attended protests and press conferences Tuesday morning with three members of Congress at the Congress.

He was arrested by homeland security personnel and was detained at another facility in Newark. The mayor was released about five hours later and was charged with breaking in.

Meanwhile, Department of Homeland Security spokesman Tricia McLaughlin told CNN Saturday morning that “there will be more arrests” after the facility protests, saying three members of Congress were arrested there – Bonnie Watson Coleman, Rob Menendez, Rob Menendez and Lamonica McCiver.

McLoughlin told CNN that lawmakers “put law enforcement at risk, which actually puts detainees in danger too,” and said the Department of Homeland Security “shots of some members of Congress attacking our ICE law enforcement officers.”

Newark sued Geo Group, which won a 15-year contract with ICE and said the company is renovating the facility without a proper permit and that city inspectors are being banned from entering the center.

Federal officials and representatives of Geo Group denied the allegations and told The New York Times that the company obtained a proper permit, calling Baraka's arrest a "mayor propaganda stunt," who also ran for state governors' campaign.

“The mayor was told that he was very welcome to the facility as long as he followed the security protocol like everyone else,” McLaurin told the Times.

During Tuesday's protests, Baraka joined Coleman, Menendez and McIver, who were allowed to access the facility as part of their oversight visit.

In a video reviewed by The New York Times, a homeland security agent told Baraka that he could not enter the facility like a member of Congress or he would be arrested.

Baraka, who was in the crowd, told Sharpton that he had left the entrance gate "several times" and was eventually arrested outside the facility gate. Baraka insists that he “has done nothing wrong”.

Baraka told Shapton that the Department of Homeland Security “treats us like a regular case.”

"I was put in a cell, gave me a shot, fingerprint, and was charged with trespassing federal crimes," Baraka said, adding that the police "treated (he) well".

Baraka stressed that the federal government did not share information about who was kept in detention.

"We don't know what's going on there, we don't know who's there. They don't allow inspectors. They don't comply with local laws," Baraka said. "They don't feel they have to go to court."
