Pinal County Sheriff Paul Babeu makes it clear in this weekend's "Sunday Square Off" that he's had it with questions about the million dollars worth of attack ads linking him to alleged abuse at a private school he once ran.

Babeu is running against Democrat Tom O'Halleran in the First Congressional District, covering much of northern and eastern Arizona. Polls in the notoriously tough-to-poll district indicate O'Halleran leads by about five points.

You can watch my full interview with Babeu, as well as interviews with Democratic Congresswoman Ann Kirkpatrick, who's opposing GOP Sen. John McCain; and Arizona Corporation Commission candidate Boyd Dunn, at 8 a.m. Sunday on 12 News.
