The Fox morning show Fox & Friends aired a four minute video attacking President Obama's term in office that was created by Fox News executives.
Fox News, which is continually criticized for its right-leaning reporting, is the highest watched news channel in the nation. This is a problem when American journalism purports itself as unbiased, and Fox news itself claims to be "fair and balanced." Fox executives claim that they had no knowledge of the video, that they dealt with it, and that they subsequently removed the video. This is not the first time that Fox has produced an attack ad against Obama; they played one before his State of the Union Address in January.
According to this article in MediaMatters,
The network helped launch the tea party movement, was instrumental in Republicans taking back the House in 2010, and basically served as the unofficial venue for the 2012 Republican presidential primary.
This brings up the question of bias in journalism--if overtly biased sources can claim to be journalism and news, can news claim to be unbiased?
