Michael Abramowitz reports for The Washington Post:
White House officials are suggesting that the general's views will carry great weight with Bush. "He is following through on his commitment to be guided by the people on the ground who know the most about what's going on," White House Chief of Staff Joshua B. Bolten said.
I might have thought it relevant at this point to note that Bush's deference to military expertise is a bit opportunistic. When, for example, the joint chiefs and Bush's previous set of commanders in Iraq didn't want a surge, he ditched them in favor of some different commanders.
