 The 30-year-old CEO in Chicago is changing the way we buy from local businesses. And trying to make billions doing it.

WASHINGTON (AP) -- It's something any bank would demand to know before handing out a loan: Where's the money going?

But after receiving billions in aid from U.S. taxpayers, the nation's largest banks say they can't track exactly how they're spending the money or they simply refuse to discuss it.

"We've lent some of it. We've not lent some of it. We've not given any accounting of, 'Here's how we're doing it,'" said Thomas Kelly, a spokesman for JPMorgan Chase, which received $25 billion in emergency bailout money. "We have not disclosed that to the public. We're declining to."

Few things stir the blood more than Wall Street firms getting into a good old scrap. Put aside the internecine squabbling at Morgan Stanley - they don't come much better than the current dust-up between Citigroup (metals "super cycle") and Goldman Sachs (oil "super spike"), and Merrill Lynch - whose chief equity strategist, David Bowers, on Monday poured water on the idea of what he described as a resources bubble.
