Many critics have argued, despite its repeated mention in the Joint Resolution, that human rights was never a principal justification for the war, and that it became prominent only after evidence concerning weapons of mass destructions and Saddam Hussein's links to terrorism became discredited. For example, during a July 29, 2003, hearing of the Senate Foreign Relations Committee, then Deputy Secretary of Defense Paul Wolfowitz spent the majority of his testimony discussing Saddam Hussein's human rights record, causing Senator Lincoln Chafee (R-RI) to complain that "in the months leading up to the war it was a steady drum beat of weapons of mass destruction, weapons of mass destruction, weapons of mass destruction. And, Secretary Wolfowitz, in your almost hour-long testimony here this morning, once—only once did you mention weapons of mass destruction, and that was an ad lib."
