The Common Council’s Land Use and Building Management Committee, which approved on Wednesday the plan to build the new Norwalk High School on the existing football field, defended CSG after some residents raised concerns about the company and its president, Jim Giuliano. In a letter sent to the Common Council and Mayor Harry Rilling on Wednesday and obtained by Hearst Connecticut Media, Giuliano defended his company and contested claims made by Norwalk parent Kelly Turner. “To the best of my knowledge, CSG is not the subject or target of the current FBI investigation. Neither the FBI, nor anyone else has alleged or even suggested any misconduct on the part of CSG or its owners in connection with the projects being investigated,” Giuliano wrote in his letter. “Moreover, Ms. Turner’s statement that ‘there is a grand jury search into Jim Giuliano’ is completely untrue. I assure you, there is no such grand jury inquiry.” Documents mentioning the East Hartford-based company, which was hired to consult in the building of the new Norwalk High School, were sought in a subpoena issued by the U.S. Attorney for the District of Connecticut to the Connecticut Department of Administrative Services.
