Sen. Duckworth, during an interview on MSNBC’s “AM Joy” with host Joy Reid, was asked about Trump’s upcoming West Point address and the protesters outside the Thompson Center in Chicago. One of the handmade signs said “Arbeit Macht Frei, JB.”

That infamous phrase, cited through the decades to remember and invoke the horror of the Holocaust, was above the main entrance gate to the German Auschwitz concentration camp in Poland. It means “work makes one free.” Pritzker is Jewish.

“That Nazi slogan is not acceptable,” said Duckworth, who is Asian American.
