The logo of US Bank is seen atop the US Bank Tower in downtown Los Angeles July 17,2012. Los Angeles has sued US Bancorp, accusing a unit of the fifth-largest U.S. commercial bank of becoming one of its biggest slumlords and blighting the city by allowing hundreds of foreclosed homes to fall into disrepair. The lawsuit alleges that US Bank NA has taken title to more than 1,500 foreclosed residential properties in the city in its role as trustee for various mortgage-backed securities trusts.
