A radio ad from a super PAC run by former aides to Sen. Harry Reid (D-NV) is tying the death of Trayvon Martin to GOP Senate candidate Thom Tillis.

The ad, a recording of which was posted online, says “Tillis even led the effort to pass the type of stand your ground laws that caused the shooting death of Trayvon Martin.”

The ad was recorded from a live airing by North Carolina-based blogger Sister Toldjah.
