The problem is that the birth announcement was not sent by the hospital, but probably by his grandmother (no doubt to legitimize the birth, although I don’t think he was born in Kenya but in British Columbia). Anybody could post a birth announcement in the paper, which didn’t check and didn’t require that it come from the hospital or some other official source.
Was it really his grandmother he lived with. No one really knows anything about these people. Well, some do for sure. I imagine that Putin knows it all, along with Pelosi, the Clintons and scores more in Congress.
