Here it is: http://www.whitehouse.gov/sites/default/files/rss_viewer/birth-certificate-long-form.pdf
And someone opened it in Adobe Illustrator and found "layers". So what? you ask?
My question is not "so what?" but "why now?"
From Wireupdate.com (4/27/2011):
When the PDF file given from WhiteHouse.gov is opened in Adobe Illustrator it shows up in different layers.
Our analysis of the latest controversy: The original birth certificate was probably in a ‘negative’ form, and someone at the White House took it upon themselves to doctor it up so the form can be readable.
