A number of DSC revocations and upgrades to the Medal of Honor were the result of reviews initiated by the Army or mandated by the United States Congress. In the early 1990s the Army began a review of discrimination against black soldiers in World War II, none of whom had received the Medal of Honor but several of whom had received lesser awards. Later, the Department of Defense Authorization Act for Fiscal Year 1996 provided for a "Review Regarding Upgrading of Distinguished-Service Crosses and Navy Crosses Awarded to Asian-Americans and Native American Pacific Islanders for World War II Service" and the National Defense Authorization Act for 2002 provided for a "Review Regarding Award of Medal of Honor to Certain Jewish American and Hispanic American War Veterans". There is currently a petition circulating to upgrade the Distinguished Service Cross of Major Richard Winters to a Medal of Honor.
