The visit caused some controversy, both in the United States and around the world, when it became known that members of the Waffen-SS, the military arm of Nazi Germany's SS ("Schutzstaffel"), were also buried there. The entire SS was judged to be a criminal organisation at the Nuremberg trials. The fact that Reagan had not been scheduled to visit former Nazi concentration-camp sites compounded the controversy, and a trip to Bergen-Belsen concentration camp was later added to his itinerary.
