It's interesting that you should post on this topic; I heard about this Citigroup deal on Monday listening to "The Mike Gallagher Show" on teh am radios here in Atlanta. The Chairman of Citigroup was asked about this and his response was something to the effect of "...well...that was a separate deal in a separate time in which both parties are contractually obligated".
What a load of horse-shit! They ought to rename it "U. S. Taxpayer Field".
