He is now likely to be held at the Metropolitan Correctional Center, a federal detention center in Lower Manhattan, while he awaits trial. He may also remain at the federal prison in Loretto, Penn., where he is serving his sentence, and brought to New York for hearings, according to the people with knowledge of the matter. The former Justice Department officials and current state prosecutors, who regularly handled the transfer of federal inmates to state custody, said they were surprised that the second-highest official in the Justice Department would take an interest in the case. The decision is usually made by the warden at the prison where the inmate is being held. Justice Department officials were unable to say who made the decision in Mr. Manafort’s case; the Bureau of Prisons, which is part of the Justice Department, did not respond to a request for comment.
