♪ this morning there is an outpouring of the messages from world leaders on the passing of senator john mccain. he was known to be a foreign policy hawk and he loved to travel constantly. >> he flew combat assignments during the vietnam war. he was shot down and spent more than 5 hellish years as a hanoi prisoner of war in a camp there. i want you to listen to senator chris coons with mccain's experience there. >> it was really remarkable, it was powerful to be in that place and to go into a cell and to see the leg shackles or the tiny little barred windows and to realize this man didn't spend a few weeks or few months, but years of his life there. i asked him a question because he had been there several years
