Joe Kennedy said the Kennedy family matriarch otherwise had a "great summer and transition into fall" where she "enjoyed time with her children, nieces, nephews, grandchildren and great-grandchildren" and "was able to get out on the water, visit the pier, and enjoy many lunches and dinners with family."
