Photographer Doug Mills on capturing bullet during Trump's rally assassination attempt

Pulitzer Prize-winning photographer Doug Mills had his finger on the shutter when a gunman opened fire during former President Donald Trump's rally on Saturday.

Mills, who was covering the rally for the New York Times, initially thought the noise came from a vehicle, but he quickly realized it was something much more serious.

"When I saw him kind of grimace and look to his right and then grab his ear, and looked at it, I thought, and then he went down. I was like, 'Oh my gosh, he's been shot'," said Mills.
