Rumsfled submitted his resignation twice and the President refused it. May be this time Rumsfled just had it and he will not accept a no from the President.
That's what I think happened.
maybe. but I didn't like the tone of the presser. I wanted to hear "I was relcuntant to accept this resignation, but sec'y Rumsfeld was adamant".
instead, we essentially heard that Bush has been considering this for a while now.
