C&Ler Nonny Mouse heard on the BBC that Bush was going to replace both Casey and Abizaid. Seems like they're getting the boot for not agreeing with the McCain Doctrine. (Here's the BBC story)
Update: I just found this in my inbox:
ABC News' Martha Raddatz Reports: ABC News has learned that the president intends to nominate Admiral William J. Fallon to replace General John Abizaid at Central Command. The announcement is expected next week, before the president gives his Iraq strategy speech, according to US officials.
Officials also tell ABC that the replacement as MNF-I commander in Iraq (replacing Gen. George Casey) will be LTG David Petraeus. Though Casey was originally staying in position till June, he is expected to leave earlier than expected probably in the next few months.
“The president wants a clean sweep” an official told ABC News.
