Mitt Romney refused to answer reporters' questions on Thursday about his support for Indiana Senate candidate Richard Mourdock, who has become the latest Republican to find himself in hot water over comments about rape and abortion.

Romney and Sen. Rob Portman (R-Ohio) stopped by a Cincinnati diner on Thursday morning. Bloomberg's Lisa Lerer and Reuters' Sam Youngman noted that when they attempted to ask the GOP presidential nominee about Mourdock, he repeatedly ignored their questions. Specifically, Romney avoided answering whether he wanted the ad pulled and if he would disavow Murdock's rape comments.
