Former Rep. Joe Heck received criticism this week after he posted a picture on Instagram of himself posing next to a slain zebra with the caption, “Great start to safari — two off my list: Zebra and Black Wildebeast.” But Heck’s apparent affinity for big-game hunting in South Africa didn’t just upset some in the public. The former Nevada Senate candidate earned a lashing from an organization he lobbied on behalf of this spring: People for the Ethical Treatment of Animals (PETA).
