An assistant U.S. attorney for the Southern District of New York said Monday that a new indictment was “likely” in the criminal campaign-finance case against two associates of Rudy Giuliani.

Assistant U.S. Attorney Douglas Zolkind—answering a question posed by U.S. District Judge J. Paul Oetken of the Southern District of New York—confirmed that the investigation into defendants Lev Parnas and Igor Fruman remained ongoing, but declined to comment any further in open court.
