Yes.
First time was a case where Zero's lawyer asked the court to take judicial notice of the "birth announcement" posted online. And went on to say the release of the birth certificate would be embarrassing
Second time was in the Terry Lakin trial. At his trial the presiding judge warned him not to ask for any Obama documents (birth certificate, etc.), for they might prove embarrassing to the President.
So tell me what is so embarrassing about his birth certificate? You know, the one he released as an electronic file on the internet claiming it be the LFBC.
