Obama's video won't even enter in to it.
If he loses his pension for this, I think he has rights to see all of Obamas documents in a civil case. I think a reasonable Judge and Jury would agree he would have standing.
In order to establish standing he has to demonstrate a link between an action by Obama and his court martial. I doubt he'll be able to do that.
A little girl from Arkansas had much less standing than this man. Much less, just her word against against a Governor and then a US President. This man has a First Lady makeing public statements that support his position. He has Kenyan Government officals makeing public statements that support his position. He has US Senators openly questioning the presidents qualifications. Once a law suit is started, its like war. Theres no guarantee you will win or lose.
