There have been rumors because he has family in Kenya. He interfered in an election there as a Senator. The interference was on behalf of someone who claims to be Obamas cousin. There have been whispers for sometime. Birthplace didn’t matter as a Senator. The bar is higher for a US President.
As a senator his birthplace didn’t matter, but he had to be a US citizen for 14 years. I want to see his I-9 form.
