The army investigation into the dismissal of Gen. Stanley McChrystal—the U.S.’s top commander in Afghanistan until June—has yielded some key questions, including who was responsible for the inflammatory quotes against the general. The inquiry has found that it was not McChrystal himself or the most senior members of his staff that made the most offensive comments that had led to his abrupt dismissal, although some blame has pointed toward a mid-level Navy special warfare officer who was not interviewed as part of the inquiry. Although McChrystal was not quoted saying anything directly insubordinate in the article, there were quotes by people identified as senior aides to the general disparaging many members of Obama’s national-security team. Gen. George Casey Jr., the Army chief of staff, ordered the inquiry to determine how Rolling Stone was granted access to a wartime general and also to find out who was responsible for the most offensive quotes. McChrystal hastily resigned immediately after the Rolling Stone interview was made public, and is now teaching at Yale University. He will appear at The Daily Beast Innovators Summit in October to moderate a CEO leadership panel.
