US pressure group Swift Boat Veterans for Truth has criticised Senator Hillary Clinton for her lack of front-line combat duty in the Vietnam war. “Where was Hillary at Khe San? Where was Hillary at Da Nang?” said spokesman John O'Neill. Swift Boats was formed to fight Democratic candidate John Kerry’s military record during the 2004 presidential race, but was criticised for being a partisan lobby with ties to President Bush's re-election campaign. The group has yet to comment on the Vietnam war experiences of leading Republican candidates Mitt Romney and Rudy Giuliani.
