The purpose of this legislation, known as the "Remove the Stain Act," is to rescind the Medals of Honor that were awarded to soldiers for their actions during the Wounded Knee Massacre on December 29, 1890. The bill aims to address the historical injustice of recognizing military actions that resulted in the deaths of unarmed Native Americans, including women and children. Key provisions of the legislation include the formal rescission of each Medal of Honor awarded for the Wounded Knee incident.
