pentagon investigating Kerry's medals and citations In a fresh blow to John Kerry's flagging presidential campaign, the Pentagon has ordered an official investigation into the awards of the Democratic senator's five Vietnam War decorations. News of the inquiry came as President George W Bush opened an 11-point lead over his rival - the widest margin since serious campaigning began - according to the first poll released since last week's Republican convention. The highly unusual inquiry is to be carried out by the inspector-general's office of the United States navy, for which Sen Kerry served as a Swift Boat captain for four months in 1968, making two tours of duty. He was wounded in action and subsequently awarded three Purple Hearts, a Silver Star and a Bronze Star. But for the past month, the exact details of Mr Kerry's military service in Vietnam have become shrouded in a controversy that the navy has now decided warrants a full-blown search for the truth. I'm sure it won't be long before the media starts in on how the investigation may have been ordered by the white house.
