Rand Paul's PAC supporting Mourdock on air

Sen. Rand Paul's RAND PAC is going up on the air with a six-figure buy backing embattled GOP Senate hopeful Richard Mourdock in Indiana starting this weekend, his team said.

The spots are centered on foreign aide and Mourdock rival Joe Donnelly's record as a congressman on that topic.

But the timing is in the middle of the controversy over Mourdock's comments on pregnancy that results from rape, and the mixed responses from national GOP figures to them.
