INDIANAPOLIS (AP) — Sen. Richard Lugar says he will not campaign for the man who vanquished him in May’s Republican primary.

Lugar told conservative Indiana blogger Abdul Hakim-Shabazz in an interview posted Monday that he would not actively support Republican Senate candidate Richard Mourdock on the campaign trail. The six-term senator had previously left the question unanswered. But he raised eyebrows in July when he introduced Mourdock to Senate Republicans at a weekly lunch.
