The police had found DSK "en fâcheuse posture" in a car in the Bois de Boulogne shortly before the 2007 presidential election. The Élysée knew and had leaked this note to the press. Claude Guéant seems to have been in charge of leaking additional information about the private life of DSK. But he was not the only politician whose sexual activities were being tracked by the Élysée.
A sad, sad, sad business. All of it.
