(JTA) – Former head of the Central Intelligence Agency and National Security Agency Michael Hayden compared the Trump administration’s immigration policies to Nazi Germany.

In a tweet posted on Saturday, Hayden wrote: “Other governments have separated mothers and children,” under a black and white photo of the front of Auschwitz as seen from the railroad tracks approaching the former Nazi camp.

The tweet is a response to reports that under the U.S. government’s so-called zero tolerance policy against illegal migrants nearly 2,000 children have been separated from their parents or adult guardians after entering the United States.
