WASHINGTON - President Barack Obama kicked off an effort to encourage US businesses to keep jobs at home instead of outsourcing them overseas, as he rolled out a new election-year theme on Saturday aimed at courting middle-class voters.

In his weekly radio and video address, Obama previewed an event he will hold next week with business executives to highlight the advantages of investing in the United States.

"We'll hear from business leaders who are bringing jobs back home and see how we can help other businesses follow their lead," Obama said.

The White House forum on "Insourcing American Jobs" will be held on Wednesday. Executives from more than a dozen companies will attend, including padlock maker Master Lock, furniture company Lincolnton Furniture, software application developer GalaxE Solutions, and chemicals company DuPont.

The emphasis on keeping US jobs at home is in line with a populist economic message championed by Obama that could play well with union workers, whose support the Democratic president will need to win re-election in November.

The White House sees an increasing trend of companies deciding to "insource" jobs and invest in US-based plants and factories, according to a White House official. It wants to encourage more businesses to follow that trend, the official said.

The practice of US companies moving jobs to foreign countries such as India and China, where labor is cheaper, is a source of concern to many US workers.

The issue resonates strongly in Midwest industrial states such as Ohio and Michigan that have been hard hit, not only by the 2007-2009 economic crisis, but also by years of shrinkage in the manufacturing jobs sector. Many of those states are battlegrounds that are vital to Obama's re-election hopes.

Republicans vying to challenge Obama in November, including front-runner Mitt Romney, have hammered him over his economic stewardship. They contend that his regulatory policies, including new rules for Wall Street and the overhaul of the healthcare system, have discouraged investment. They also say his fiscal stimulus measures have not succeeded in bringing down high unemployment.

But the White House was encouraged by the December jobs report, released on Friday, which showed a drop in the jobless rate to 8.5 percent, its lowest level in nearly three years.

"We're heading in the right direction. And we're not going to let up," Obama said.?
