CNN.com - Powell unsure whether WMD will be found in Iraq

"I think the answer to the question is 'I don't know yet,'" Powell told reporters. "Last year, when I made my presentation, it was based on the best intelligence that we had at the time. It reflected the National Intelligence Estimate that the intelligence community had presented to all administration officials and had briefed to the Congress. And it was consistent with the views of other intelligence agencies of other governments, and it was consistent with the body of reporting over the years."
