Whenever you add the word NOT to a thing, you include everything else in the universe. So, if there is NOT known evidence, you have an infinite universe of possibilities to occupy your delusional imagination.
Funny, I thought when you added NOT to a thing you had nothing.
Was he born in the US? I think it is a valid question. Absent the original certificate, the only way to determine his place of birth is to look for evidence (ie facts, not because he says so) to prove or disprove. I hardly call that delusional.
Producing the original birth certificate could shut this down right away and save alot of money in billable hours. Makes no sense to me.
Oh, and factcheck? Since when is that a reliable source?
