NEW YORK — Federal prosecutors said Wednesday that they might bring additional charges against New York City Mayor Eric Adams and indict others in the corruption case against him. Prosecutors made the disclosure as Adams appeared in court for a hearing days after he was indicted on charges that he accepted about $100,000 worth of free or deeply discounted international flights, hotel stays, meals and entertainment from foreign interests, and obtained illegal campaign contributions.
