Argentinian Senate's Expenses by La Nacion

After finding out that Senate have published expenses since 2004 in raw PDFs, some of them as images and completely unstructured, LA NACION data team managed to scrape, transform, normalize and structure three datasets into one and began an interrogation process that included front page stories, replies from actual and former Argentina´s vice presidents (Senate presidents), and provoked a judicial investigation over vicepresident Amado Boudou regarding these expenses.
