Speaking at the National Press Club, Donald Trump proposed a new theory about Obama's birth certificate. Trump conceded there's a "very big chance" Obama was born in America but said he believes Obama lied about being born in Kenya to get into college.
Asked if he "regretted" questioning Obama's birth certificate, Trump said he did not regret it "even a little bit."
In spring of 2011, Trump flirted with the idea of his own presidential run, with his platform centering around exposing President Obama's fraudulent citizenship and Kenyan birth. His loud birtherism — and the constant media attention it attracted — was enough to put him on the top of some early Republican primary polls. Trump ultimately decided not to run.
