Fox News says Mike Brown has been removed from Katrina duties.

Fox cites AP. That's all I know.

UPDATE: CNN says,

FEMA director Michael Brown being sent back to Washington; Homeland Security Director Chertoff to announce new leader for on-the-ground Katrina relief efforts, senior administration official tells CNN. Details soon.

I'm expecting not Rudy Giuliani, Jimmy Carter, or Colin Powell, but a well-regarded milquetoast, quite possibly with no related experience, but someone who won't show The Big Guy up.

UPDATE: Here's the AP story. Brown stays in his FEMA job, but is no longer working on Katrina recovery.

Brown will be replaced by Coast Guard Vice Adm. Thad w. Allen, who was overseeing New Orleans relief and rescue efforts.

Allen was recently designated Michael Chertoff's Katrina deputy. He seems well regarded.

Though, given the nature of the Commander in Chief, I half-suspect he was promoted not for his skills, but for his knee-slappers:

Vice Adm. Thad W. Allen, head of the Coast Guard, had his own contribution to the finger-pointing debate Thursday.

Appearing on ABC's "Good Morning America," Allen, who has been tasked to assist in the recovery efforts, said, "I give Mother Nature an F."

Har-de-har-har.
