The Obama campaign is taking aim at GOP presumptive nominee Mitt Romney's running mate, Rep. Paul Ryan, over an abortion bill he co-sponsored with embattled Rep. Todd Akin.
The move is part of an attempt to link the Wisconsin lawmaker to controversial remarks Akin made about about rape.
The measure, which won the support of 225 other House members, used the term "forcible rape." It was designed to prevent taxpayer funded abortion.
Ryan faced questions about the bill's language in an interview with local Pittsburgh television station KDKA.
"Rape is rape," Ryan told KDKA. "And there's no splitting hairs over rape."
In another interview, Ryan said he stood behind his pro-life record.
"I'm proud of my record," Ryan told reporters aboard his campaign plane. "Mitt Romney is going to be president. The president sets policy. His policy has exceptions for rape, incest, and life of the mother. I'm comfortable with it because it's a good step in the right direction."
When it comes to the women's vote, President Obama enjoyed a 13-point lead over Sen. John McCain, R-Ariz., in the 2008 presidential election.
Pollsters predict he will need an even bigger margin to win this year's race against Romney.
