Of course he knew there weren’t WMD, the entire war is about oil. Iraq threatens to stop selling us oil, or threatens to increase prices, and we invade. But obviously, Bush is not going to tell us that American soldiers are dying so that your cars can run in the morning; he says soldiers are dying because there are weapons that can hurt our wonderful country. Of course, us citizens, willing to believe anything that the president says, go along with it until, some six years later we figure out there were no WMD’s at all.

So yea, he knew there weren’t any WMD, but he needed a coverup.

My information comes from too many sources to list, I would say mostly from my government class-which should be considered an unbiased source.
