I thought, however, that I had clarified to the relevant bodies in a timely manner regarding the management of funds for PdL's parliamentary group in the Senate,'' said Gasparri. ''The transaction in question was proposed to me by the bank that has always had its offices in the Senate and everything was done with great transparency and in the interest of the party,'' Gasparri continued. Gasparri declared that the legal proceedings caused him ''great distress and hardship, but I have a clear conscience because, as always, I operated with integrity''.
