Good stories always seem to feature complex characters. Today we hear the real-life story of Reverend Rob Schenck, a national conservative leader who has led crusades against abortion — but now questions whether being pro-life squares with being pro gun. We talk with the director behind a new documentary about Schenck called “The Armor of Light.” Also, it’s World AIDS Day and we hear about a treatment program for teens with HIV that pairs young adults with dogs. Also, the season finale of Tyler Perry’s TV series “If Loving You Is Wrong” airs Tuesday night on Oprah Winfrey’s OWN network. We talk with one of the stars, Chicago-native Eltony Williams. We also have another installment in our My Life in Three Songs series.
