Obama's latest jobs push appeared timed to steal back the spotlight and draw a contrast with Republican presidential front-runner Mitt Romney, whose rivals have accused him of once being a ruthless corporate raider who laid off US workers and shipped jobs overseas. Highlighting what the White House touts as a growing trend but which some economists say has yet to gather much steam, Obama put the focus on businesses that have chosen to "in-source" jobs from abroad and urged others to follow their lead. "In the next few weeks, I will put forward new tax proposals that reward companies that choose to bring jobs home and invest in America and we're going to eliminate tax breaks for companies that are moving jobs overseas," Obama told business leaders and state and local officials. The White House declined to give specifics about the new ideas but repeated its call for Congress to enact some of those already put forth, including making a research and development tax credit permanent, allowing businesses to write off new equipment and providing a hiring credit for adding new workers. Any new tax initiatives would require approval by Congress, where the Democratic president faces continued stiff resistance on tax policy from his Republican foes.
