Schieffer: Trump's Racist

Donald Trump has moved on from the "birther" conspiracy to allege President Barack Obama didn't get good enough grades to warrant entry to Harvard Law School, an assertion that CBS News chief Washington correspondent Bob Schieffer called absurd on the "CBS Evening News" on Wednesday.

"That's just code for saying he got into law school because he's black. This is an ugly strain of racism that's running through this whole thing. We can hope that kind of comes to an end too, but we'll have to see," Schieffer said.

Trump first raised the issue on Monday with the Associated Press, saying: "I heard he was a terrible student, terrible. 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."
