US President George W Bush is facing fresh charges that he exaggerated the threat of Iraq's alleged weapons of mass destruction to win support for the war. In a strong attack on Bush's administration, Democratic Senator John Kerry accused the president misleading everyone. Kerry, a leading contender to contest the 2004 presidential election for the Democrats, promised that Congress would get to the bottom of the matter. Committees in both houses of the US Congress are continuing private inquiries into the issue, but on the ground in Iraq no stocks of weapons of mass destruction have so far been found. The Bush administration built its case for war around its contention that Iraq had WMD, and has recently faced increasing political and public questioning of its motives.
