Democratic U.S. Senate candidate Alexi Giannoulias sought to blunt a potentially damaging political issue today about questions regarding his involvement in his family’s struggling bank, which he said he expects will likely fail in the coming months. But questions were still left unanswered following a more than 70-minute meeting with the Chicago Tribune’s editorial board. Among them were exactly what Giannoulias knew about convicted bookmaker Michael Giorango’s criminal past when he received loans from Broadway Bank, and how many of the bank’s troubled loans were made while Giannoulias was working there.
