The assassination

on former President Donald Trump immediately sent shock waves across the nation

and through an already tense presidential campaign.

It also quickly became an event defined by iconic photographs. We spoke to two of the photo

journalists who were covering Mr. Trump's rally in Pennsylvania that day and who are

now here in Milwaukee for the Republican National Convention.

And you know that's a little bit old, that chart's a couple of months old.

I had my lens trained on the stage and over my left shoulder I heard several pops.

And I knew right away it was gunfire. So I ran to the stage and I pulled

my wide angle lens out and I started photographing. I just really tried hard to just keep on

taking pictures, just keep on taking pictures.

Just keep on taking pictures.

My name is Anna Moneymaker, and I'm a staff photographer

for Getty Images in Washington, D.C.

My name is Evan Vucci.

I'm the chief photographer for AP in Washington. My name is Evan Vucci. I'm the chief photographer for AP in Washington.

in American history.

And I have the responsibility to cover it.

The entire time I'm thinking, okay, slow down,

slow down, think, compose.
