FoxNews:  “The Obama administration took the unprecedented step Friday of clearing the way for banks to do limited business with marijuana sellers, releasing guidelines for how financial institutions can work with pot shops in states where it’s legal.  The move immediately was greeted with relief from the budding marijuana industry. Before the guidance, banks largely had avoided the new pot shops in Colorado for fear of federal prosecution — leaving marijuana sellers running cash-only operations. . . . It’s unclear, though, to what extent banks will engage those businesses. One industry group, the Consumer Bankers Association, voiced legal concerns despite the new guidelines and urged Congress to get involved.”
