WASHINGTON, May 9 -- Raoul Wallenberg was made a United States honorary citizen in 1981 for his work saving thousands of lives during the holocaust. Wallenberg worked to issue passports to Jewish families declaring them Swedish so they could escape the Nazis. Wallenberg went missing during World War II and died in a Russian Prison in 1947. Last year, Wallenberg was awarded the Congressional Gold Medal for his achievements. The medal was unveiled today at the Treasury Department by Treasury Secretary Jacob Lew, King of Sweden Carl XVI Gustaf and Rep. Gregory Meeks, D-N.Y.
