UPDATE: The New England Police Benevolent Association has denied involvement in a Donald Trump rally attended by supporters wearing Ku Klux Klan robes.

Previously:

Amid the chaos of the Nevada caucus were people dressed in the traditional hoods and robes of the Ku Klux Klan, holding up signs pledging their support for Donald Trump.

At least one person in KKK clothing held a sign expressing support for the New England Police Benevolent Association — a group that endorsed Trump in December.

The people in Klan robes were photographed by a number of attendees outside the Cimarron-Memorial High School location in Las Vegas.

“KKK in parking lot of Cimarron HS during Republican caucus. They keep saying take our country back. I have never ever seen this in Las Vegas. I’m speechless,” one witness wrote on Instagram.

Senator Aaron D. Ford, a minority leader of the Nevada state senate, also tweeted his disgust over the display.

The outcry on social media over the hooded figures did not diminish Trump’s support, however, as the GOP frontrunner won the Nevada caucuses by a landslide.

The billionaire real estate mogul has now won three straight states, after topping the field in New Hampshire and South Carolina. Florida Sen. Marco Rubio and Texas Sen. Ted Cruz were still battling it out for second, with Rubio in the lead.
