She claims to have a birth certificate "from the United States of America."
But she doesn't.
The United States of America doesn't issue birth certificates. Seriously, try to get one.
They will direct you to the state in which you were born.
And with at least 2 dozen different states (I've lost count--how many Virginias again?), that means many different looking birth certificates (they're like drivers licenses, or snow flakes). So just cause hers doesn't look like his, doesn't make his not real.
Watch her false claim here.
