Former U.S. diplomat Manuel Rocha is facing charges of spying for Cuba since 1981. He was arrested in Miami on Friday and charged with federal crimes, including acting as an illegal foreign agent and using a fraudulently obtained passport. Rocha had his initial court appearance on Monday and will remain in custody until his bond hearing on Wednesday. The U.S. government plans to bring additional charges against him. Authorities discovered Rocha’s activities through undercover operations, where he revealed information about his involvement with the Cuban government. The case is being described as one of the highest-reaching infiltrations of the U.S. government by a foreign agent.
