The inability of the U.S. to find weapons of mass destruction in Iraq has led to greater domestic criticism of the administration's Iraq policy. Several of the statements that Bush and his administration made leading up to the war in Iraq, especially those involving claims of Iraqi weapons of mass destruction, have been criticized as misleading or inaccurate. Particularly controversial was Bush's claim in the 2003 State of the Union Address that British Intelligence had discovered that Iraq was seeking to buy uranium from Africa. Officials and diplomats disputed the evidence for this claim, especially after a document describing an attempted purchase from Niger, which was presented to the United Nations Security Council by Colin Powell, was found to be a forgery. This led to a public embarrassment for George Tenet, the director of the CIA, as well as the Valerie Plame scandal. Much criticism on these issues has come from political opponents of Bush. The Iraq war was a significant issue in the 2004 Democratic primary, including the campaigns of Howard Dean, John Kerry, Al Sharpton, and Dennis Kucinich.
