 I'm Scott Detrow. Ahead, we'll talk to the New York Times photographer who captured an image of the bullet whizzing by Trump's head. We'll also hear from one of the country's top presidential historians about how this might change the campaign and the country's political mood. I always go back to can we find perspective? Can we find lessons? Are there something to learn from the past? And we'll look forward to the Republican National Convention, which begins tomorrow in Milwaukee.
