I don't trust Graham, but I found the timing of his trip to Italy interesting and the fact that according to Papadopolous, Trump called the Italian PM last week. Nunes mentioned last night that they are seeking more info on Mifsud. Everything points to him being associated with Italian intelligence. The fact that Mifsud owned 35% of Link University, which was founded by a former Italian Minister of the Interior, indicates that Papadopolous was correct in saying it was a place where spies were trained.
You should read the article. Very informative from the Italian media.
