Maliki's government secretly supporting Shia militias

This story about a secretive "Commander in Chief" office within Maliki's government that is being used to protect the Shia militias actually broke yesterday, but I find today's CNN version fills out some of the questions I had.

The Office, as it is known in Baghdad, was set up about four months ago with the knowledge of American forces in Iraq.....

Every senior U.S. and Iraqi military official who spoke to CNN in Baghdad about the advisers asked not to be named due to the sensitive nature of the story and potential political or personal backlash.

A White House official confirmed that the U.S. government does have specific concerns about the Office, adding: "We are working with them on their command-and-control issues to make sure it works properly and so that commanders are put into their jobs for the right reasons and not just sectarian reasons."

This was set up under Casey and Khalilzad with White House approval, and I find it very curious that this story comes out of Baghdad right after Petraeus and his staff come back from Washington. (Did they not get the White House response they wanted?)

Or is this lower level officers understandably angered because they're busting their butts and Maliki is working against them?

There's just something about this story and the way it's coming out that tells me the sourcing is very important.

The White House knew about this problem from its inception and "senior US military officials" requested anonymity out of fear of "political or personal backlash."

There's something here.
