Sure. Call in his family fi you want. Some of them said he was born in Kenya. Thats fine. But the most important thing here are the docs.
I agree with you that the documents are the most important factor in resolving the issue.
My point is that there are also other factors and witnesses that have had custody of those documents that are also important. For example, wouldn’t you want to ask if the Obama birth records have ever been amended or altered?
Wouldn’t you want to ask whether the State of Hawaii ever issued that short form COLB to Obama and when?
