 I'm Grinnell Scott. The assassination attempt on former President Donald Trump leaves many questions to be answered by the Secret Service and local law enforcement. It also has Americans unsteady as they march toward the polling booths in November. In a moment when people were probably shell-shocked and terrified, he wanted to telegraph to them, I'm tough, I'm okay. We now know, and watching the video back, he's holding up his fist and saying, fight.
