HARRISBURG, Pa. (AP) - Millions of dollars flooding into Pennsylvania's U.S. Senate race is bringing TV ads on abortion and guns into living rooms barely 11 weeks before the election.

In August alone, at least six groups began airing new TV ads in the hotly contested race between Republican incumbent Pat Toomey and Democratic challenger Katie McGinty.An ad by billionaire Michael Bloomberg's group shows the daughter of the principal slain in the 2012 mass shooting in Connecticut's Sandy Hook Elementary School. She says she's grateful for Toomey's willingness to defy GOP leaders on legislation to expand gun background checks.Meanwhile, a Planned Parenthood ad shows Toomey in a 2009 television interview. In it, he says he'd support legislation to ban abortion in Pennsylvania and impose penalties on doctors who perform them, even jail.
