The Jewish Community Relations Council of New York strongly condemned Rep. Alexandria Ocasio-Cortez, D-N.Y., for comparing U.S. immigration policies to Holocaust concentration camps in a letter they sent to her Tuesday.

The New York Democrat accused U.S. immigration officials of running “concentration camps” on the U.S. southern border in an Instagram video Monday night. Ocasio-Cortez made a call to action to “the people that are concerned enough with humanity that ‘Never Again’ means something,” referencing the phrase used about the Nazi genocide.
