Buchenwald Concentration Camp Memorial Prepares For Obama Visit

WEIMAR, GERMANY - JUNE 04: A barbed wire fence stands on the grounds of the former Buchenwald concentration camp on June 4, 2009 near Weimar, Germany. U.S. President Barack Obama is scheduled to visit the site tomorrow. Obama's great-uncle, Charles Payne, was among U.S. soldiers who liberated the nearby subcamp of Ohrdruf in 1945. Thousands of Jews and other inmates died under horrendous conditions at the Buchenwald camp during World War II. (Photo by Sean Gallup/Getty Images)
