"Of course, what is important is not what the majority thinks, but the facts that will emerge as a result of a fair trial. Of course, I and tens of thousands of people who have been subjected to such a serious accusation want to clear our name and be acquitted through a fair judicial process. We do not want to live with such suspicion cast upon us. Unfortunately, especially since 2014, due to the political control of the justice system, my right to exonerate myself and the accused Hizmet sympathizers have been taken away. Therefore, I make an open call to the Turkish Government and promise full cooperation. I demand that an international and independent commission investigate the coup attempt. If they prove even one tenth of the allegations against me true, I am ready to return to Turkey and suffer the heaviest punishment."
