A study by two nonprofit journalism organizations found that President Bush and top administration officials issued hundreds of false statements about the national security threat from Iraq in the two years following the 2001 terrorist attacks. (Source)
I'm pleased to see that the study didn't let the enablers of those lies off the hook:
"Some journalists — indeed, even some entire news organizations — have since acknowledged that their coverage during those prewar months was far too deferential and uncritical. These mea culpas notwithstanding, much of the wall-to-wall media coverage provided additional, 'independent' validation of the Bush administration's false statements about Iraq," [the study] said.
Although, at least judging from the news article, there is another group of enablers who escape unscathed - the Democrats and Republicans in Congress.
