FED Injected 70 bn

FED Injected 70 bn into the market in the morning, and then in the afternoon FED asked JPM and other banks to get 75 bn for AIG? Is there connection between them?

If yes, AIG might can get that 75 bn it needs in time, and then market flies?

I have no position, just think why FED is so cool this time to LEH and AIG?
