DES MOINES, Iowa -- Republican presidential candidate Mitt Romney is criticizing President Barack Obama's handling of the national debt in Iowa, a Midwestern battleground he hasn't visited since the state's leadoff nominating caucuses.
Romney's speech Tuesday in Des Moines is expected to promote spending discipline. That's a turn from the social issues that marked the campaign last week.
Obama announced on Wednesday that he supports gay marriage, then Romney reiterated his opposition to same-sex unions.
Romney has argued that the nation's debt is choking the economic recovery and has criticized Obama for spending programs including the 2009 economic stimulus and the 2010 health care overhaul.
Obama's campaign aired a new television ad accusing Romney of costing jobs at a Kansas City, Mo., steel mill that his company failed to restructure.
