Gawker discovered this correction from the Wall Street Journal:
NEWS CORP.'S Fox News was incorrectly described in a page-one article Monday as being sympathetic to the Bush cause.
...and then points us to an AFP story where Murdoch says Fox News isn't biased, but his newspapers will continue to support Bush's foreign policy. As for charges of bias, Murdoch knocks them out of the park with this 1+1 = 1 answer: "We're not in the least bit biased, we're a fair and balanced company, our slogan is fair and balanced."
Slate also has an interesting take on the correction. (And, to be fair, it looks like they noticed it first.)
