The advertisement began with a photo of Representative Alexandria Ocasio-Cortez bursting into flames, followed by a black-and-white image of skulls lined up on the ground.

The provocative advertisement, which warned about socialism by invoking the murderous Khmer Rouge movement in Cambodia, was paid for by a Republican political action committee and aired during the Democratic primary debate on Thursday night.

The televised commercial came weeks after the shooting in El Paso, where a white nationalist killed 22 people in the deadliest massacre targeting Latinos in modern American history. Since El Paso, many Latinos have said they fear for their safety, worried about future attacks by white supremacists.

The group that paid for the ad, New Faces GOP, states on its website that its mission is to “help elevate the next generation of Republicans” and recruit more diverse candidates.
