Secret Service agents sprinted to Hillary Clinton's side Thursday during a rally in Las Vegas after a group of protesters got too close for comfort.

The demonstrators, a group of animal rights activists, crossed the barrier near Clinton's podium, and heckled her as they carried signs bearing slogans that included, "Until Every Animal Is Free."

Four secret service agents rushed the stage to get to Clinton, and quickly surrounded the Democratic presidential candidate as she took a break from her address.

"You're okay," one agent told Clinton. "Keep talking. We'll handle it. We're not going anywhere. Keep talking, ma'am."

Clinton approached the microphone and said, "Okay, we're going to keep talking."

"Apparently, these people are here to protest Trump," she added. "Because Trump and his kids have killed a lot of animals, so thank you for making that point."
