Donald Trump's rally in Las Vegas on the eve of the next GOP debate turned chaotic on Monday night as protesters shouted slogans and audience members screamed back.
Trump was interrupted several times by protesters shouting slogans supporting gun control and "Black lives matter!," prompting a furious reaction from the crowd. Some screamed, pointed, and at one point shoved a heckler as hotel security swooped in to remove them.
The first protests began after Trump invited Jamiel Shaw, a supporter, to the stage to recount how he lost his son after an undocumented immigrant gang member shot him while walking home. One protester who shouted in response that the story showed the need for gun control was promptly removed by professionals, a scene that played out repeatedly through the night.
As one man was dragged away, people in the crowd variously yelled, "Shoot him!" "Kick his ass," and "Light the motherf----r on fire!"
A large middle aged man shouted, "Sieg heil!" — a Nazi Germany-era salute — as the protester was taken away. The man, whose motives were not clear, was far enough from the stage that it was unlikely Trump heard the remark.

The man who was removed as remarks above were shouted, Ender Austin III, told Buzzfeed News he was upset about Trump's remarks towards Muslims, a group the candidate has proposed temporarily barring from entering the country. He said he was not arrested after being taken from the venue and placed in police custody.
"He's a Muslim!" another man in a glittering black suit shouted as another protester was removed. "He's a Muslim!"
Trump took the interruptions in stride and complained that they were the only way to get media outlets to turn their cameras towards his crowds to show off their size.
The confrontation at Trump's rally comes on the eve of the final televised prime time Republican presidential debate of the year. Trump, who is the GOP field's front runner according to a recent NBC News/Wall Street Journal poll, is expected to be a target once again when nine top Republican candidates take the stage in Las Vegas Tuesday night.
A spokeswoman for the Las Vegas Police Department told NBC News that 15 to 20 people "attempted to disrupt the event, were escorted out, trespassed off property, but no arrests were made."
