That was not "the media is lying". Miller used Bush administration sources and confirmed with an Iraqi source that turned out to be the source of the Bush info. Its disputed whether she was misled by one or both of these sources or perhaps one of the sources misled the other. That the administration would rely on this reporting, rather than their own CIA which was calling it into question, is a reflection on their deception not the media's.

It was bad reporting that was compounded by the editors not pushing back, as the article you cite goes on to say.
