Rep. Alexandria Ocasio-Cortez accused the Trump administration of housing immigrants in concentration camps on the Mexican border and used the phrase “never again” that is associated with the Holocaust.

​”​The United States is running concentration camps on our southern border and that is exactly what they are – they are concentration camps – and if that doesn’t bother you,” Ocasio-Cortez said as she throws up her hands.

​”​I want to talk to the people that are concerned enough with humanity to say that we should not — that ‘Never Again’ means something,” ​the New York Democrat said in a Q&A posted on politicsnowadays’ Instagram page.

​Ocasio-Cortez, a self-described Democratic socialist, went on to call President Trump a “fascist” for carrying out such policies against immigrants. ​

​​“I don’t use those words lightly. I don’t use those words to just throw bombs,” ​she continued. “I use the word because that’s what an administration that creates concentration camps is.​ A presidency that creates concentration camps is fascist and it’s very difficult to say that.”

O​casio-Cortez on Tuesday tweeted a link to an Esquire article from last week that quoted a University of Virginia lecturer saying that concentration camps have a far larger meaning than usually associated with the Nazis during World War II.

“Things can be concentration camps without being Dachau or Auschwitz. Concentration camps in general have always been designed – at the most basic level – to separate one group of people from another group,” the report quoted Waitman Wade Beorn as saying. “Usually, because the majority group, or the creators of the camp, deem the people they’re putting in it to be dangerous or undesirable in some way.”

Ocasio-Cortez also blasted the administration for planning to temporarily place 1,400 migrant children in Fort Sill in Oklahoma, the same facility used as an internment camp for Japanese Americans during World War II.

“This is not just about the immigrant communities being held in concentration camps being a crisis, this is a crisis for ourselves,” she said. “This is a crisis on if America will remain America – its actual principles and values – or if we are losing to an authoritarian and fascist presidency.”

​The Department of Health and Human Services, which announced the use of Fort Sill last week, said it has taken into custody nearly 41,000 children through the end of April — an increase of 57 percent over last year. ​

Officials also considered using other federal facilities in Montana and Georgia as temporary shelters to house the expanding number of children crossing into the US, but they weren’t available.

The Obama administration also used Fort Sill to hold nearly 2,000 migrant children in 2014 because of a surge of immigrants at the time.
