At 12:41 AM (Eastern), a piece appeared in the Newsbusters.org feed with the title "9/11 WAS AN INSIDE JOB." The article itself consisted of three words: "IT WAS OhBAMA." (Note: the article had already been removed from the website by the time I saw it and was only visible in the RSS feed). I sent a quick note to Newsbusters to confirm that the site was indeed hacked, as seemed readily apparent and received the following response from Matt Sheffield:

Yes it was a hack. We've since blocked the attacker and removed the defaced content.

We're currently investigating the situation but the site should be functioning as normal at this time.

Thanks for your email.
