"We're not saying he's changed his mind on these issues," Cutter said. "We're saying he's trying to cover up his beliefs."
Cutter said the campaign would seek to make sure that women are "not fooled" by Romney's attempts to soften his positions on abortion. The Democrat's campaign has aired TV ads accusing Romney of supporting overturning Roe v. Wade and eliminating federal funding for Planned Parenthood.
"Women frankly just can't trust Mitt Romney," Planned Parenthood President Cecile Richards said on the Obama campaign call. Richards said she was taking a break from her role at the women's health services provider to volunteer for Obama in the campaign's closing weeks.
Romney did not seek to clarify his abortion comments during a day of campaigning Wednesday in Ohio. He noted at a town hall-style meeting that his wife, Ann, and Karen Buchwald Wright, the businesswoman who helped introduce him, were breast cancer survivors.
"Karen was kind to remind me that this is Breast Cancer Awareness Month and gave me this pin, which I am wearing this morning in her honor and the honor of my wife and in honor of all the women across America who have battled this terrible disease and know of our commitment to defeat it and to provide long lives to our fellow citizens," Romney said.
Romney called the women "champions."
