Just wondering why he got the boot, and why there was hardly any coverage of the change-over. I would have thought it more news-worthy that it seems to have been.

In browsing for info, I came across this site - no punches pulled here! Did they (or others of similar opinion) make a difference?

When reporters asked him, how long does he think he will need in order to accomplish his mission here, he said he would be in Iraq "as long as it takes," and that he planned to finish rapidly.

(CNN) -- Retired Army Lt. Gen. Jay Garner, interim U.S. administrator of Iraq, will turn over command "within weeks" to former U.S. diplomat L. Paul Bremer III, appointed Tuesday as presidential envoy to the country, a senior Defense Department official said Sunday.
"It has been the plan all along that once Bremer got his feet on the ground" that Garner would give up his role, the official said.
Garner had said early on that he expected his term would last about three months, but this transition comes at a time that would cut that to about two months.

A defense official acknowledged, however, that Garner's status as a retired U.S. military officer had created a perception that the U.S. military was controlling the effort to create an Iraqi government.
Also, the official said, there has been tension between the State Department and the Pentagon over what to do in Iraq and Bremer "could bridge that gap."
Other administration sources told CNN they hope Bremer, with 23 years of diplomatic service, will be more politically astute than Garner, who was criticized for not traveling immediately to Baghdad as the war effort was winding down and civilian needs were growing.
