Asked about the Mitt Romney Bain story, president Obama responded:

 Well, here’s what I know, we were just talking about responsibility and as president of the United States, it’s pretty clear to me that I’m responsible for folks who are working in the federal government and you know, Harry Truman said the buck stops with you.

Okay then, so President Obama is responsible for: Solyndra, Fast and Furious, the GSA scandal…oh you fill in the rest.
