Donald Trump is upping the ante against President Barack Obama's legitimacy, raising questions on Monday night about how the president was admitted to two Ivy League schools.
Trump openly questioned how Obama, who he said had been a "terrible student," got accepted into Columbia University for undergraduate studies and then Harvard Law School.
"I heard he was a terrible student, terrible," Trump told the Associated Press in an interview, a claim he's made in the past but one he doubled down on by suggesting he's probing that area of the president's life.
"How does a bad student go to Columbia and then to Harvard? I'm thinking about it, I'm certainly looking into it. Let him show his records," he said, without providing backup for his claim.
Trump added, "I have friends who have smart sons with great marks, great boards, great everything and they can't get into Harvard."
"We don't know a thing about this guy," Trump said. "There are a lot of questions that are unanswered about our president."
