Maybe next time they can carpool? The CEOs of Goldman Sachs and Morgan Stanley and the chairman of Citigroup missed their meeting with President Obama on Monday after their commercial flight was held on the tarmac due to fog. The meeting, in which Obama is expected to pressure banks to loosen up their lending, had already lost some of its luster when Citigroup CEO Vikram Pandit pulled out and announced he would be sending the chairman in his stead. All three men were able to participate, however, by conference call. JP Morgan CEO Jamie Dimon flew by private jet and was expected to be there on time.
