Mitt Romney is defending his time as a business executive, saying that he ultimately added tens of thousands of jobs despite cuts at some companies.
Romney on Thursday night acknowledged that he cut jobs at some of the businesses his venture capital firm took over. He says that some of his investments didn't pay off and that not all businesses succeed.
His chief rival, Newt Gingrich, has accused Romney of shredding companies and costing Americans jobs. Romney says that he worked to help businesses strengthen themselves and survive.
Romney also says that he welcomes the criticism and predicts that President Barack Obama will use it against him if Romney wins the Republican nomination.
Romney made the remarks during the latest GOP debate.
