Interim U.S. Attorney for the District of New Jersey, Alina Habba, was cautioned by a federal magistrate judge not to make out-of-court statements regarding Democratic Newark Mayor Ras Baraka following his arrest.

Baraka was arrested last month for trespassing outside an immigration detention center in Newark, New Jersey, where he and three members of Congress were attempting to gain access.

U.S. Magistrate Andre M. Espinosa cautioned officials in the Trump administration against making statements about Baraka outside of court. Espinosa emphasized the need to “heed carefully the rules of professional conduct” and reminded them of the “boundaries of propriety for public comment related to an ongoing investigation and/or prosecution.”

Earlier that day, Habba, a longtime personal attorney to President Donald Trump, had posted on social media, stating that the mayor had “willingly chosen to disregard the law” and had “committed trespass” before his arrest last week at an Immigration and Customs Enforcement facility in Newark.

During the hearing, Espinosa also ruled that Baraka was not a flight risk.

“It doesn’t take me much effort to assess the facts here and conclude that the mayor of the largest city in New Jersey poses no substantial flight risk or no flight risk at all and no danger to the community that must be protected against any conditions,” Espinosa said.
