At a rally in Tampa, Florida, Trump supporters attacked CNN reporter Jim Acosta, prompting the president to double down on his anti-press “Enemy of the People” rhetoric. A look at how and why the president incites his base — and where it all might lead. And, as the regulatory battle surrounding 3D gun blueprints rages on, we dive into the worldview of Cody Wilson, the man who started the controversy. Plus, why we’re still living in the aftermath of Trayvon Martin’s killing, six years later.
