The Bush administration advocated for war by hyping the case ("smoking gun to be a mushroom cloud") and feeding the public selective information. They knew that a lot of these claims (including the 16 words) were from questionable sources, but they pushed them on the public anyway, while downplaying the evidence to the contrary. Perhaps that's not literally a "lie," but its certainly dishonest, especially given that those claims, in fact, ended up being untrue.
