According to Wikipedia:
Mario Draghi [became] vice chairman and managing director of Goldman Sachs International and a member of the firm-wide management committee (2002–2005). [...] Pascal Canfin (MEP) asserted Draghi was involved in swaps for European governments, namely Greece, trying to disguise their countries' economic status. Draghi responded that the deals were "undertaken before my joining Goldman Sachs [and] I had nothing to do with" them, in the 2011 European Parliament nomination hearings.
While it is not disputed that the deal was initiated before he joined the company, should he have had any supervisory role over the team that arranged it, it would have been expected that he rectify the wrongdoing, starting by disclosing it to the public. Not only that, but the maturity of the deal was extended in 2005, before he took up a new appointment at Bank of Italy, which was not given due attention. During the hearing, this career public servant provided an interesting explanation supporting his claim that he had no connection to the deal and its follow up : out of personal preference, he did not interact with the public sector. This is contradicted by an official statement from his employer. Oddly, a request by a renowned news agency to have access to some relevant documents were blocked by the ECB shorty before the scheduled hearing.
