Facing a wave of withering attacks from Obama and his allies over massive job losses at companies controlled by Bain Capital under his watch, the presumptive Republican presidential candidate lashed back for the first time this week in a speech in Washington and an interview with Time magazine.

“Sadly, President Obama has decided to attack success. It’s no wonder so many of his own supporters are calling on him to stop this war on job creators,” Romney said as he began an education policy address before the Latino Coalition’s annual economic summit at the U.S. Chamber of Commerce.

Earlier Wednesday, in an interview with Time’s Mark Halperin, Romney said he welcomes scrutiny of his business career.

“The fact is that I spent 25 years in the private sector, and that obviously teaches you something that you don’t learn if you haven’t spent any time in the private sector,” Romney told Halperin.

Romney added: “You learn through life’s experience. The President’s experience has been exclusively in politics and as a community organizer. Both of those are fine areas of endeavor, but right now we have an economy in trouble, and someone who spent their career in the economy is more suited to help fix the economy than someone who spent his life in politics and as a community organizer.”
