Republicans are claiming outrage after Rep. Alexandria Ocasio-Cortez (D-N.Y.) compared immigration detention centers along the southern border to concentration camps—remarks she first made during an Instagram Live session late Monday and has since defended.

“That is exactly what they are: They are concentration camps,” Ocasio-Cortez told her followers on Monday. “I want to talk to the people that are concerned enough with humanity to say that ‘never again’ means something.”

Rep. Alexandria Ocasio-Cortez (D-N.Y.) created a new political firestorm Tuesday, stating that detention centers housing immigrants are “exactly” like concentration camps and then doubling down in the face of GOP criticism.

“The U.S. is running concentration camps on our southern border, and that is exactly what they are,” Ocasio-Cortez said during an Instagram Live appearance on Monday night.

“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.”

The vice president of the National Border Patrol Council extended Democratic New York Rep. Alexandria Ocasio-Cortez a personal invitation to tour a detention facility after she claimed that the U.S. government is “running concentration camps on our southern border” to hold illegal immigrants.

“She needs to come down here, I’ll offer to show her myself the area,” Art Del Cueto, vice president of the National Border Patrol Council and a Border Patrol agent, told Bill Hemmer Tuesday while appearing on “America’s Newsroom.”
