Pope Francis named one of Italy’s leading anti-Mafia prosecutors as president of the Vatican’s criminal tribunal Thursday, just days after a new scandal erupted over alleged financial wrongdoing in the heart of the Holy See. The appointment of Giuseppe Pignatone came two days after Vatican police raided the Apostolic Palace and seized documents and computers from the secretariat of state. Also searched were the offices of the Vatican’s financial watchdog agency, which is tasked with flagging possible money laundering and other suspicious financial transactions.
