Rep. Alexandria Ocasio-Cortez defended her statement that the U.S. is running concentration camps on the southern border by saying the U.S. also ran concentration camps during World War II.

“There is a very clear academic consensus on what constitutes a concentration camp and that is the mass detention of a community of people without a trial or due process,” the New York Democrat told CNN’s Manu Raju on Tuesday. “I think it’s pretty universally not controversial to say that the administration is doing exactly that and meets the academic requirement for what a concentration camp is.”
