Based on an anonymous complaint, in early 2011 the Department of Defense Inspector General began investigating allegations that Stavridis "engaged in misconduct relating to official and unofficial travel and other matters." He was subsequently the subject of a May 3, 2012, report by the Inspector General, and was later absolved of wrongdoing by the Secretary of the Navy on September 11, 2012. In a Memorandum for the Record, Secretary of the Navy Ray Mabus wrote that Stavridis: "has consistently demonstrated himself to be a model naval officer and a devoted public servant whose motivation is to do that which is necessary and appropriate to advance the interests of the United States." Mabus concluded that "I have determined that ADM Stavridis never attempted to use his public office for private gain nor did he commit personal misconduct."
