You don't seem to get it, so let me explain. It's generally in the best interest to not indulge lunacy. No President prior to Obama has ever released a birth certificate, but Obama released one. Then people clamored for this "long form" birth certificate. He ignored at first, but the lunacy continue, and eventually he had to request that the state of Hawaii circumvent their own laws to release the long form. And then the crazies start saying passport, school records. Which are additional things that NO President has ever released or ever even been asked to release. He's learned that if he gives in again, they'll find some other new thing. And in the end it's all more of this birther nonsense, which as we all know is rooted in racism and xenophobia.
Why doesn't Trump take Colbert up on his $1million offer to have Colbert dip his balls in Trump's mouth? It's a million dollars to a charity of Trump's choice?
