text:  The suspected gunman was killed yesterday. A Trump supporter was also killed. He's been identified as Corey Comporator, a firefighter. Chris Potter is the political editor at member station WESA in Pittsburgh. Thanks for joining us, Chris. Thank you for having me. So this rally was in Butler, about 30 miles north of Pittsburgh. You were watching a feed of the rally while a colleague of yours was there. What did you and your colleague hear in the aftermath of the shooting?
