US Gov to give Citigroup another $20billion, how could they have afforded Wacovia

So far, Citigroup was given $25 billion last month. Now they are getting an additional $20 billion. Yet just a short time ago, they were trying to buy Wacovia. Does anyone know where the money to buy Wacovia would have come from?

However, in a New York Times story dated 09 October 2008:

It’s been downhill ever since.[/li][/ul]
Where would the money have come from? From an exchange in stock that no longer has value.

Also, the purchase of Wachovia would have given Citigroup a dramatically increased deposit base in the United States which might well have prevented the current crisis of confidence in Citi.
