SAN JUAN, Puerto Rico (AP) — A federal immigration judge in Miami has ruled that Pierre Réginald Boulos, a wealthy Haitian businessman and one-time presidential hopeful, will not be released from a detention center where he’s being held after the U.S. government accused him of supporting violent gangs in Haiti. Thursday’s hearing was held behind closed doors, with authorities barring journalists and others from the courtroom and the detention center itself. It wasn’t immediately known what occurred at the hearing, other than the judge ordering that Boulos remain held. That’s according to a person familiar with the case. U.S. Immigration and Customs Enforcement arrested Boulos at his Florida home in mid-July in a move that shocked many.
