> According to a report by The Globe and Mail in November 2023, Spavor sought a multimillion-dollar settlement against the federal government for involving him in espionage activities without his knowledge. Spavor alleged that he provided Michael Kovrig with intelligence on North Korea, which Kovrig then secretly gave to the Canadian government and its Five Eyes allies without Spavor's permission, leading to their arrest and detention
I'm surprised that we don't hear more about this from the American government and media.
