Romney campaign spokeswoman Andrea Saul said Wednesday that Romney disagrees with Mourdock's opposition to abortion in cases of rape and incest. But she says Romney still supports Mourdock's bid.
Mourdock made the comment during a debate Tuesday night with his opponent, Democratic Rep. Joe Donnelly.
Romney recorded a TV ad supporting Mourdock's bid that began airing in Indiana this week. A Romney official said the campaign has not asked Mourdock to stop airing the ad.
Democrats have called on Romney to disavow support for Mourdock and pull down the TV ad.
