The post itself contains a fascinating historical precedent that maps pretty well to the current situation:
Knut Hamsun (Literature Prize 1920): In 1943, the Norwegian author Knut Hamsun travelled to Germany and met with Propaganda Minister Joseph Goebbels. After returning to Norway, he sent his Nobel medal to Goebbels as a gesture of thanks for the meeting. Goebbels was honoured by the gift. The present whereabouts of the medal are unknown.
