Those documents being forged do not prove he was born outside the U.S. There are many possible reasons for that. If the President was born somewhere else, shouldn't all these people searching for it, found some tangible proof by now? It's hard for me to imagine they wouldn't have by now.
Is it legal for a presidential candidate to present false documentation of his/her eligibility to run for and hold the office of POTUS?
“Those documents being forged do not prove he was born outside the U.S.”
The documents being forged do not prove he was born ‘inside’ the U.S. either.
