He testified in one big case, still ongoing, to the pool of prosecutors that investigates the negotiations between the Italian State and the Mafia.

At the request of the public prosecutor Nino Di Matteo Naimo's dry reply came: "Of the safe masonry". "Riina always talked about it ... there was a notary freemason very friend of Riina ...". The reference of the collaborator of justice was directed to Giuseppe Mandalari, known as the "accountant of Totò Riina", founder of many lodges covered in Sicily, who had personally supervised various affairs of the Corleonese bosses. "There were these Masonic relations - specified Naimo - that in turn these Masons had relations with politicians". The collaborator then stressed that Mandalari himself sought "political adhesions".
