From yesterday's Washington Post, "Bush Remarks Confirm Shift in Justifying War":

"We found the weapons of mass destruction," Bush asserted in the Thursday interview, released Friday. "We found biological laboratories. You remember when Colin Powell stood up in front of the world, and he said, Iraq has got laboratories, mobile labs to build biological weapons. They're illegal. They're against the United Nations resolutions, and we've so far discovered two. And we'll find more weapons as time goes on. But for those who say we haven't found the banned manufacturing devices or banned weapons, they're wrong. We found them."

Bush's assertion, one of many recent administration statements shifting focus from Iraq's weapons to Iraq's weapons programs, indicated the president would consider its accusations justified by the discovery of equipment that potentially could be used to produce weapons. But the original charges against Iraq, presented to the United Nations and the American public, were explicitly about the weapons themselves.
