The LA Times reports that it will be the Bush White House:
Despite Bush’s repeated statements that the report will reflect evaluations by Petraeus and Ryan Crocker, the U.S. ambassador to Iraq, administration officials said it would actually be written by the White House, with inputs from officials throughout the government.
The president actually presaged his own views at the recent press conference. One would imagine the president’s views will feature prominently in any report authored by the White House.
THE PRESIDENT: As you know, General Petraeus and Ambassador Crocker will be coming back to report on the findings of the success of the surge. The surge success will not only include military successes and military failures, but also political successes and political failures. And my own perspective is, is that they have made some progress, but not enough.
So the findings on the success of the surge will feature both successes and failures. And, no doubt the president will ask for more time to reach our ultimate objective of Victory.
