Local financial institutions have officially launched their fundraising effort to address food insecurity.  After comedian John Oliver pledged $55,000 to teachers, Connecticut Food Bank and ALS, three banks put together seed money to benefit United Way’s Danbury Food Collaborative.  Union Savings Bank, Savings Bank of Danbury and Newtown Savings Bank put up $45,000 and opened a website for donors to also contribute.  Their goal is to raise $100,000.  Mayor Mark Boughton says two people have also already donated $500 each for tours he will lead of the sewer plant.  The bank leaders say the coronavirus pandemic has increased demand for food in the area, with some pantries serving three times as many households as they were before.  More than 24 agencies in the area are part of the Danbury Food Collaborative, including 14 food pantries and congregate meal programs.
