WASHINGTON (August 7, 2012)--A super PAC that supports President Barack Obama is launching a new television advertisement critical of Republican Mitt Romney's business record at Bain Capital.

The ad, sponsored by the political action committee Priorities USA Action, features a former employee of GST Steel who lost his job and health insurance when Bain closed the Kansas-based steel plant in 2001.

The man says he doesn't think Romney "understands what he's done to people's lives" by closing the plant.

The ad is the fifth in a series of spots from Priorities targeting Romney's business record, the centerpiece of the presumptive Republican nominee's campaign.

The ad is running in the battleground states of Florida, Ohio, Iowa, Virginia and Pennsylvania.

Mr. Obama is set to attend fundraisers Tuesday evening in the District of Columbia.

Romney was raising campaign money Tuesday in Illinois.
