Citigroup is "a Big Government lovers' bank that funds just about every trendy left-wing cause in America," says Matthew Vadum:

Long before it started drowning in red ink, the poster child for so-called corporate social responsibility was a longtime donor to left-wing pressure groups such as Jesse Jackson's Rainbow/PUSH Coalition and Henry Paulson's Nature Conservancy. In tax year 2003, Citigroup's foundation gave 20 times more money to groups on the left than to groups on the right, according to Capital Research Center's 2006 study of Fortune 100 foundation giving. . . .
Citigroup's foundation has given a staggering $1.4 million to the alarmist World Resources Institute, as well as $509,000 to ACORN in recent years. The ACORN funding included a $500,000 grant to ACORN's American Institute for Social Justice, which offers Saul Alinsky-style training in community organizing. Other donations to liberal groups include the Aspen Institute ($762,500), Rainbow/PUSH ($750,000), Nature Conservancy ($380,000), Rainforest Alliance ($200,000), and the Council on Foreign Relations ($50,000).
