President Obama says "the buck stops" with Mitt Romney for his time leading Bain Capital, and he should answer the questions that have been raised about his time there.

In an interview with WJLA-TV to be broadcast Sunday, Obama had this to say today:

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. Now, my understanding is that Mr. Romney attested to the SEC, multiple times, that he was the chairman, CEO and president of Bain Capital, and I think most Americans figure if you are the chairman, CEO and president of a company, that you are responsible for what that company does. Ultimately, Mr. Romney, I think, is going to have to answer those questions, because if he aspires to being president, one of the things you learn is, you are ultimately responsible for the conduct of your operations. But again, that's probably a question that he's going to have to answer, and I think that's a legitimate part of the campaign.

The president addressed the Bain controversy on a day when Romney was taping interviews on the subject with the five major broadcast and cable TV networks. The interviews are to be aired later tonight.

BLOG: Romney offensive

Romney's career at Bain has been central to his campaign as an economic Mr. Fix-It. But of late, he has been fending off allegations that Bain took over companies involved in outsourcing jobs, and that he stayed involved with Bain three years longer than previously believed.

Obama's campaign was almost as quick as the TV station in tweeting out the president's remarks. Within minutes, Ben LaBolt and Danny Kanner from Obama for America had tweeted, as well as the Democratic National Committee's Brad Woodhouse.
