"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? How would you dress up DHS’s mass separation of thousands children at the border from their parents?" she asked.

Ocasio-Cortez first made the concentration camps comment late Monday while on Instagram Live talking about the Trump administration's housing of immigrants near the southern border.

“The U.S. is running concentration camps on our southern border, and that is exactly what they are," she said. “If that doesn’t bother you ... I want to talk to the people that are concerned enough with humanity to say that ‘never again’ means something."

She clarified during her livestream that she did not use the phrase to "just throw bombs."

Concentration camps were used by the Nazis to hold Jews and other political prisoners and groups deemed by the government to be undesirable without trial under harsh conditions.

Immigrants detained illegally crossing the U.S.-Mexico border are often held before immigration or asylum trials.
