Rep. Alexandria Ocasio-Cortez sparred with her Republican House colleagues on Tuesday after the New York Democrat ​compared housing conditions for immigrants at the border to concentration camps.

​”Please @AOC do us all a favor and spend just a few minutes learning some actual history. 6 million Jews were exterminated in the Holocaust​,” wrote Rep. Liz Cheney of Wyoming on Twitter. “You demean their memory and disgrace yourself with comments like this.​”

Rep. Lee Zeldin called for Ocasio-Cortez to “stop trying to draw these crayon parallels between POTUS & Hitler!”

“Try working WITH your colleagues on BOTH sides of the aisle to secure our border & fix this rather than desperately trying to promote mass hysteria w this disgusting & woefully false comparison,” the Long Island Republican said on Twitter.

Their comments came after a video of Ocasio-Cortez ​aired on politicsnowadays’ Instagram page that showed her accusing the Trump administration of running concentration camps on the US border with Mexico and referring to President Trump as a “fascist.”

Ocasio-Cortez shot back at Cheney minutes after her posting.

​”Hey Rep. Cheney, since you’re so eager to ‘educate me,’ I’m curious: What do YOU call building mass camps of people being detained without a trial?” the first-term lawmaker said. “How would you dress up DHS’s mass separation of thousands children at the border from their parents?”

The online spat launched reams of comment on the social messaging site about concentration camps and death camps, leading Rabbi Danya Ruttenberg to weigh in.

​”Ok, Internet. Time to learn the difference between concentration camps and death (“extermination”) camps. Germany started with concentration camps in 1933. Death camps started in 1941. Never again is now​,” Ruttenberg, the ​author of “Surprised by God: How I Learned to Stop Worrying and Love Religion,” wrote on Twitter.
