 It's Morning Edition from NPR News. I'm Steve Inskeep. And I'm Sasha Pfeiffer. We still don't have a clear understanding of why a gunman tried to assassinate former President Donald Trump on Saturday. So some people are coming up with their own reasons. The shooting happened in the middle of a presidential campaign that was already saturated with conspiracy theories and threats of political violence. We're joined now by NPR's Elisa Hagan and Adet Youssef. Both of you, thanks for being here this morning.
