President Barack Obama said on Friday that the Buchenwald concentration camp "is the ultimate rebuke" to those who deny the Holocaust. Obama visited the Nazi-era camp where 56,000 people died. He toured the memorial Friday with German Chancellor Angela Merkel and survivor Elie Wiesel. They laid roses at a memorial. Obama said people today have a duty to confront those who deny such concentration camps existed.
