ABC: Bush set to replace Abizaid, Casey.

President Bush “intends to nominate Admiral William J. Fallon to replace General John Abizaid at Central Command” and Lieutenant General David Petraeus to replace General George Casey as Baghdad commander. “The president wants a clean sweep” an official told ABC News. “Fallon, who is in the Navy, is currently head of Pacific Command; he will be overseeing two ground wars, so the appointment is highly unusual.”
