I dunno....both he and Gibbs admitted posting the document on the net.
Posting the document means nothing.
If you don’t think that ‘deny-ability’ hasn’t been planned from the beginning, then you don’t know Obama.
Even proving the document is a forgery won’t prove that Obama knew about it or that there isn’t a ‘real’ BC out there.
BUT, if they can prove that the documents were fake, then they will have a better shot at getting at any records (or lack thereof) of O’s.
