A 1993 study commissioned by the United States Army investigated racial discrimination in the awarding of medals. During the investigation it was determined that one Veteran American Jew and Holocaust survivor, Tibor Rubin, had been the subject of discrimination due to his religion and should have received the Medal of Honor. In 2005, 55 years later, President George W. Bush presented the Medal of Honor to Rubin in a ceremony at the White House, for his actions in 1950 during the Korean War.
