Debra - D'Souza did not intimate that David Walker was blaming Obama for the deficit. Walker's comments illustrated "specifically" that our debt is out-of-control (no blame specified) and we need to reel it in now - not next term.
Dinesh D'Souza answers your inappropriate use accusation of Walker during an interview with another left-leaning media outlet NPR which is no better the San Francisco Chronicle.
D'Souza is quoted as saying: "The interview with David Walker was on the specific topic of debt and I don't attribute to David Walker the argument of the film or even my view that Obama uses debt as a form of global re-distribution. So, we don't misrepresent him in any way, he doesn't claim we do."
Your suggestion is False.
