"Polish death camp" controversy

"On May 28 of last year, President Obama stood next to Prime Minister of Poland in Warsaw and declared he would support new rules to help more Poles get tourist visas to the United States. “If you’ve lived in Chicago and you haven’t become a little bit Polish,” Mr. Obama joked, “there’s something wrong with you.”A year later, the president made himself the target of a searing denunciation by Mr. Tusk after he referred on Tuesday to a “Polish death camp,” instead of a Nazi death camp in Poland, in bestowing a Presidential Medal of Freedom on , a hero of the Polish resistance to the Germans during World War II. Mr. Obama was guilty of “ignorance, lack of knowledge, bad intentions,” Mr. Tusk said."
