A bank that received $1.6 billion dollars of the government’s bailout money sponsored what reports are calling a lavish series of events in Los Angeles, California, last weekend. Northern Trust, based in Chicago, Illinois, spent an undisclosed amount of money sponsoring a Professional Golf Association tournament and associated client events, including concerts, dinners and parties, according to celebrity Web site TMZ.com. The bank spent millions of dollars on the event, which included — on top of the sponsorship costs of the Northern Trust Open tournament — concerts by Sheryl Crow and Earth Wind & Fire, a private party at music venue House of Blues and gift bags from Tiffany & Co., the Web site said
