Presumptive Republican Presidential nominee Mitt Romney's career at a private equity firm has become a major point of contention for the two campaigns.

FOX News Radio's Jared Halpern has more from America's Election Headquarters in Washington:

From America's Election Headquarters.

LaBolt: "Romney was in business to make money for himself and his investors."

Obama Campaign Press Secretary Ben LaBolt argues Mitt Romney's time at Bain Capital deserves to be examined.

LaBolt: "It's where he brought and bankrupted companies, laid off workers, and shipped jobs overseas, all to turn a quick profit."

The response from the Romney Campaign?

(online video) "Have you had enough of President Obama's attacks on free enterprise?"

A new online video highlighting praise of Bain Capital, from Obama surrogates.

Booker: "I'm not about to sit here and indict private equity."

Newark, New Jersey Mayor Cory Booker has since back-tracked from those comments on NBC's "Meet The Press".
