Justin Elliott tracks this ridiculous "Obama is a Muslim" video:
There is no evidence presented that this Egyptian interview ever happened. And the YouTube video itself (which was apparently put up not by Lipkin, but by one of his fans) could well be the product of a lone conspiracy theorist. Which makes it all the more remarkable that it has racked up 2.5 million views.
The referral data accompanying the video shows that it has been overwhelmingly viewed in the United States and has circulated primarily through email (the main referral domain is mail.yahoo.com), rather than, say, right-wing blogs. This is a true viral video.
