A new GOP super-PAC called New Faces ran an ad during Thursday's Democratic primary debate where an image of Rep. Alexandra Ocasio-Cortez of New York was set on fire before warning of "the horrors of socialism."

Narrated by former Republican House candidate Elizabeth Heng of California, she describes Ocasio-Cortez in the ad as "the face of socialism and ignorance."

"Mine is a face of freedom, my skin is not white, I'm not outrageous, racist, nor socialist. I'm a Republican," Heng concludes.

Ocasio-Cortez tweeted, "Republicans are running TV ads setting pictures of me on fire to convince people they aren't racist. Life is weird!"

Records from the Federal Election Commission show the group is largely financed by Heng's former campaign backers.

A new GOP super-PAC called New Faces ran an ad during Thursday's Democratic primary debate where an image of New York Rep. Alexandra Ocasio-Cortez was set on fire before warning of "the horrors of socialism."

Narrated by former Republican House candidate Elizabeth Heng, who describes Ocasio-Cortez in the ad as "the face of socialism and ignorance."

Then it transitions to gruesome images of the Cambodian genocide of the 1970s, calling it the product of socialism.

"Mine is a face of freedom, my skin is not white, I'm not outrageous, racist, nor socialist. I'm a Republican," Heng concludes.

The ad immediate triggered criticism and derision. Ocasio-Cortez tweeted, "Republicans are running TV ads setting pictures of me on fire to convince people they aren't racist. Life is weird!"

She later called it "a love letter to the GOP's white supremacist case."

Heng shot back at the New York representative, tweeting, "Not Republicans. Me. Are you really calling me a racist @aoc? I'm calling all Democrats out for supporting an evil ideology. Or are you just in Congress to hang out with celebrities and tweet out ridiculous ideas like the green new deal?

Heng was referring to the genocidal deaths of up to 2 million Cambodians under the Khmer Rouge regime in the late 1970s, when these communist insurgents took power in a civil war and then proceeded to torture and kill their political opponents and kill en masse ethnic minorities in a Nazi-like quest for racial purity. Ocasio-Cortez has said riots for injustice are understandable, but has not called for political violence.

Records from the Federal Election Commission show the group is largely financed by Heng's former campaign backers.

The controversial spot triggered a wave of criticism for ABC, the network that aired it. Ocasio-Cortez blasted ABC in a Friday morning tweet, saying "they profit from burning my likeness on TV" and lambasting it for amplifying "displays of violence."

Heng was viewed as a promising Republican candidate during the 2018 midterms. She drew on her family's roots in Cambodia to position herself as someone capable of winning over immigrant communities the GOP has long struggled with.

She lost her race to Democratic incumbent Rep. Jim Costa by a margin of 54 to 46 percent.
