PITTSBURGH (AP) _ The Democratic presidential candidates have been sparring over trade policy Monday.
Barack Obama is questioning the sincerity of Hillary Rodham Clinton's criticism of free trade agreements, noting that the North American Free Trade Agreement was passed while her husband was president.
Clinton says her husband "does make mistakes," and vowed to fix NAFTA or get out of it.
Some voters say NAFTA has taken away U.S. jobs.
Obama said political candidates will promise voters anything around election time. But he said a candidate can't "spend the better part of two decades" campaigning for free trade agreements then come to Pennsylvania "and tell the steelworkers you've been with them all along."
